Calcified Cerebral Emboli, A “Do Not Miss” Imaging Diagnosis: 22 New Cases and Review of the Literature

Fellows’ Journal Club August 2014

(2 of 3)

The prevalence, imaging appearance, presumed source, treatment, and outcome of patients with calcified cerebral emboli on CT were assessed in 22 cases seen by the authors and in 48 from the literature. Most calcified emboli were found in the middle cerebral artery territory and were thought to arise from the heart, aortic arch, or carotid plaques. The overall prevalence of these emboli was 2.7% with 27% initially misdiagnosed and 9% overlooked on the first interpretation.

Effect of Direct Neuroradiologist Participation in Physician Marketing on Imaging Volumes in Outpatient Radiology

Editor’s Choice August 2014

(2 of 3)

This study assessed the benefits of using a sales representative and a neuroradiologistas a marketing and sales team for referrals in outpatient imaging. When referring practices were visited by the 2-person team, referral volumes were 2.5 times greater than when they were visited by the sales representative alone. This impact on imaging referral volumes with the use of the neuroradiologist for direct physician-to-physician marketing supports the concept that neuroradiologist visits are important in establishing and maintaining a relationship with the referring clinician’s office and maximizing imaging referrals.

Magnetic Resonance Imaging in Movement Disorders

Tuite P, Dagher A, eds. Magnetic Resonance Imaging in Movement Disorders: A Guide for Clinicians and Scientists. Cambridge Medicine; 2013; 291 pgs; $150.00

Magnetic Resonance Imaging in Movement Disorders--Dr. Paul TuiteMovement disorders is a subspecialty of neurology, with expertise directed to disorders that affect the central control of movement. Such diseases and syndromes are frequently accompanied by manifestations of a different nature, such as cognitive, behavioral, and emotional dysfunctions. In some cases, such as in dystonias and the tic disorders, sensory information processing contributes to their clinical phenomenology and raises pathophysiological possibilities.

Conventional MRI has been of immeasurable value to the fields of stroke neurology, neuro-oncology, … Continue reading >>

Critical Findings: Timing of Notification in Neuroradiology

Fellows’ Journal Club August 2014

(1 of 3)

These authors attempted to determine the time between identification of a critical finding and verbal communication with the primary caregiver. Ninety-one critical findings identified by trainees and attending physicians were analyzed. The mean time from study acquisition to critical finding discovery was 62 minutes and from then to a telephone call was 3.7 minutes (direct caregiver communication within 15 minutes for 94% of cases). During night or weekend shifts, mean notification times increased and sources of delay were inaccurate contact information, physician unavailability (shift change/office closed), patient transfer to a different service,

Transforaminal versus Intra-Articular Facet Corticosteroid Injections for the Treatment of Cervical Radiculopathy: A Randomized, Double-Blind, Controlled Study

Editor’s Choice August 2014

(1 of 3)

In this prospective study, patients with cervical radicular pain were assigned to receive CT-guided transforaminal or facet dexamethasone injections and their outcomes were measured at 4 weeks postprocedure and compared with data collected prior to injections. Patients who had facet injections experienced significant pain reduction scores when compared with those who underwent transforaminal injections. Thus, facet injections are an effective treatment of cervical radiculopathy and represent a valid and safer alternative to transforaminal injections.
