Along with high quality and affordable access to healthcare, there is great attention placed on patient comfort.  With that in mind, the Eastgate location upgraded to a completely Open High-Field MRI in March of this year.  The Open MRI allows claustrophobic patients to have a relaxing and stress free experience, while providing state-of-the-art high field diagnostic imaging at the same time.  

“We listened to our referring physicians and the need for a high field imaging option for their claustrophobic patients,” says Dr. Stephen J. Pomeranz, CEO and Medical Director of ProScan Imaging.

Most recently, in June, the ProScan Family of Companies relocated and opened the doors of its newest Tri-State imaging center at 568 Centre View Blvd., in Northern Kentucky. The upgraded Northern Kentucky center provides exceptional care and service, featuring a new 3 Tesla MRI, as well as state of the art CT and digital X-Ray technology.

“We are excited to add this cutting edge technology and expand our services to patients of Northern Kentucky.” says Dr. Pomeranz. 

Arriving at any of the freestanding centers is easy with convenient parking in front. From the moment you enter the door, there is a clean and welcoming check-in area, with an experienced radiology technologist ready to take care of you.  Dr. Pomeranz and his expert team of subspecialty-trained radiologists review each patient’s scan providing timely and accurate results, eliminating the need for repeat imaging. 

With eight locations around the Tri-State, there is a ProScan Imaging center located within 15 minutes of nearly every home and workplace address.  The flexible appointment times, including evening and weekend appointments, help accommodate all patient’s schedules, whether they are busy students, working parents or seniors.

“ProScan will continue to build on its trusted name by focusing on investing in our community and pairing our patients with the highest level of service and professional experience,” says Mike O’Brien, President and Chief Operating Officer of the ProScan Family of Companies.

On Oct. 25, 2019, a little more than a month after the Department of Justice determined it would not intervene and closed its investigation into the whistleblower complaint against ProScan Imaging, the Relators who initiated the claim formally withdrew their lawsuit. The DOJ concurred, and a federal judge formally dismissed the case.


Update: On 10/25/19, the lawsuit against ProScan Imaging was dismissed.

On Wednesday, September 11th, the Department of Justice declined to intervene in a whistleblower complaint filed by a competitor against ProScan Imaging. The complaint alleged that ProScan utilizes non-physicians in place of radiologists. This is completely untrue.

Here are the facts: The U.S. Department of Justice thoroughly investigated the allegations. We cooperated fully, including answering every question and providing every document requested. The result: The DOJ declined to pursue the lawsuit and closed its investigation. The DOJ made that determination last week, which resulted in the unsealing of the complaint against ProScan (the unsealing of these allegations is standard practice).

To set the record straight:

  • 100 percent of ProScan cases are read by licensed, board-certified physicians. Period. No exceptions.
  • ProScan has never had a malpractice judgment in our 30 years in business.
  • ProScan has complied with Medicare regulations throughout our 30 years in business. ProScan has, and always will, treat its Medicare responsibilities with the utmost seriousness.
  • ProScan currently has more than 400 employees, including 38 full-time, board-certified physicians. We have one part-time and one full-time physician assistant on staff.
  • All physicians and clinical support personnel, including PAs, perform activities that fall within the parameters of their professional credentials.

Our business is built on trust, high-quality medical care, and exceptional service. We always act with the highest integrity. We want our patients, our referring physicians, and our radiology clients to know that nothing has changed. We are the same group of professionals providing expert, high- quality radiology services.

Three visits, two modalities, and one ankle… Go!

This 64-year-old female fell approximately three weeks ago, and presents with right ankle pain.

Prior to this incident, this patient’s foot was assessed in 2015 and 2017. Images 1 and 2 are radiographs of the patient’s foot from 2015. Images 3 and 4 are radiographs of the patient’s foot from 2017. Images 5 and 6 are MRIs of the patients foot from the current visit (2018).

Q1 – From images 1 through 6, what do you think the most likely diagnosis would be?

A1 – The most likely diagnosis is a full-thickness tear of the peroneus longus tendon. The diagnosis can be made using plain film radiographs. The os peroneum, noted on the 2015 and 2017 exams (images 7 through 10, green arrows), is fractured and distracted on the 2017 study (images 9 and 10, blue arrows).

Followup MRI in 2018 confirms a complete full-thickness tear (image 11, blue arrow). The fracture of the os peroneum is most clearly identified on sagittal images (image 12, green arrow).

*Given how uncommon fractures of the os peroneum are, they may be mistaken for bipartite or multipartite sesamoids. Typically, association of such fractures are with either acute or chronic peroneal longus tendon dysfunctions where:

  • Acute – Result from peroneal longus tendon rupture upon injury
  • Chronic – Degeneration / Tearing resulting from friction of fragments along the tendon

With distal peroneus longus ruptures, displacement and proximal migration of an intact os peroneum can be seen.

Conservative or surgical treatment methods may include:

  • Conservative – Casting, soft dressing, and steroid injections
  • Surgical – Excision of fragments complemented by repair of associated peroneal longus tendon abnormalities

Pearl: Very small tears of the peroneus longus tendon may be seen as the tendon passes around the os peroneum and prove highly symptomatic.

Bone marrow edema within the L3 and L4 vertebral bodies nearly encompasses the entire L3 vertebral body and the majority of the L4 vertebral body, and is associated with hyperintense signal within the intervertebral disc. Patient is post left laminotomy at this level. Edema and swelling track along the left laminotomy site.

After administration of intravenous contrast, the surgical site was enhanced via enhancement of the paravertebral soft tissues along the intervertebral disc space (image 7, pink arrows), anteriorly. Furthermore, extensive abnormal heterogeneous signal within the thecal sac, starting at the level of L2-L3 and extending to the sacrum, has peripheral enhancement with central low signal (image 3, purple arrow).

Patient history also indicated discitis osteomyelitis at the L3-L4 level. Combination of these findings are compatible with discitis / osteomyelitis at L3-L4 with a prevertebral soft tissue collection, involvement of the epidural space along the left laminotomy site dorsal aspect of L3-L4, and an enhancing intradural abscess extending from L2-L3 to the sacrum.

Vertebral body heights are preserved. There is a loss of intervertebral disc space height at L3-L4 with active inflammation and edema. Remaining intervertebral disc space heights are preserved with varying degrees of mild disc desiccation.

The thoracolumbar junction is intact. Spinal canal is mildly congenitally narrowed with subtle retrolistheses of L3 on L4, and L4 on L5.

Conus medullaris is visualized at L1-L2. Cauda equina nerve roots are displaced and irregular extending from the conus to the distal thecal sac due to the intradural soft tissue and fluid collection.


Clinical considerations as you might report them:

T12-L1: There is no focal disc herniation or spinal canal stenosis. The neural foramina are patent. Mild facet arthropathy is indicated.

L1-L2: There is no focal disc herniation or spinal canal stenosis. The neural foramina are patent. Mild facet arthropathy is indicated.

L2-L3: There is no focal disc herniation or spinal canal stenosis. The neural foramina are patent. Bilateral facet arthropathy is indicated. Cystic soft tissue within the thecal sac at this level extends to the distal thecal sac.

L3-L4: Patient is post remote left laminotomy at this level. Bilateral facet arthropathy is indicated. Irregular cystic soft tissue within the thecal sac is present without high grade spinal canal stenosis. Left neural foramen is moderately narrowed. Right neural foramen is mildly narrowed.

L4-L5: Subtle retrolisthesis of L4 on L5 with a shallow concentric spondylotic disc displacement. Irregular soft tissue within the thecal sac extends towards the sacrum. Bilateral facet arthropathy encroaches upon the neural foramina resulting in mild-moderate foraminal narrowing.

L5-S1: Shallow concentric disc displacement without spinal canal stenosis. The neural foramina are patent. Bilateral facet arthropathy. Abnormal soft tissue and enhancement within the thecal sac extends towards the sacrum.

Present is left paraspinal muscle edema, and enhancement along the surgical tract at the level of L3-L4 left laminotomy site.

Visualized soft tissues of the abdomen and pelvis are grossly unremarkable.


Conclusion as it might appear:

  • Discitis / osteomyelitis at L3-L4 with anterior prevertebral phlegmonous changes
  • Edema and enhancement tracking along the left laminotomy site at this level
  • Associated abnormal heterogeneous peripheral enhancing soft tissue / fluid within the thecal sac from the level of L2-L3 extending to the sacrum compatible with intradural abscess
  • Mild spondylosis

Then Wrisberg said, “That tears it!”

This 19-year-old male presents with left knee pain. The patient had an anterior cruciate ligament (ACL) repair three years prior.

When looking through the images, think about the following questions:

Q1 – What is a common pitfall when diagnosing meniscal tears of the posterior horn of the lateral meniscus?

Q2 – How can a Wrisberg rip be diagnosed with confidence?

Q3 – What major injury is associated with a Wrisberg rip?

Q4 – Vertical posterior sliver tears adjacent to the capsule of the medial meniscus are associated with which major injury?

As hinted, this case is that of a Wrisberg rip. A Wrisberg rip can be difficult to accurately diagnose. There is normally a cleft between the Wrisberg ligament (images 7 and 8, yellow arrows) as it attaches to the posterior horn of the lateral meniscus (images 7 and 8, pink arrows), and this cleft of high signal can be misdiagnosed as a tear. However, when abnormally high signal extends beyond the posterior root, and into the posterior horn towards the body, a pathological tear can be diagnosed with confidence.

In this case, the coronal images clearly demonstrate lateral extension of high signal towards the lateral posterior horn / body junction over a length of 2 to 3cm (image 6, blue and red arrows). It can also be traced with its oblique orientation from anterosuperior to posteroinferior on the sagittal images (images 1 – 5, green arrows) along its mediolateral length, confirming the pathological nature of this finding.

A Wrisberg rip is associated with anterior cruciate ligament rupture. In this case, the patient has a ruptured anterior cruciate ligament graft (image 9, orange arrow).

Also associated with anterior cruciate ligament rupture, is a vertical sliver (“linear”) tear, or peripheral rim tear, adjacent to the posterior and medial capsule (image 10, purple arrow; image 11, green arrow) of the body and posterior horn of the medial meniscus. Whether these meniscal injuries occurred with the initial anterior cruciate ligament rupture, or subsequent rupture of the graft, is indeterminate. However, a chronic time frame is favored. You can often tell if these tears are new by their higher signal, and more intense swelling around them.


A1 – Attachment of the Wrisberg ligament onto the posterior horn of the lateral meniscus can produce a high signal cleft that can be misdiagnosed as a tear, but is actually a normal variant. It’s typical course is anterosuperior to posteroinferior.

A2 – When abnormal signal is seen to track from the posterior root through the posterior horn and towards the body. In other words, the normal Wrisberg reflection is only seen on one or two sagittal slices.

A3 – Anterior cruciate ligament rupture.

A4 – Anterior cruciate ligament rupture.
