Michael J. Morris, MD, on Prostate Cancer: Impact of PSMA-Targeted Imaging on Clinical Management

Jun 1st, 2020 - Michael J. Morris, MD, of Memorial Sloan Kettering Cancer Center, discusses phase III data from the CONDOR trial, which showed that PSMA-targeted PET scans detected and localized occult disease in most men with biochemically recurrent prostate cancer presenting with negative or equivocal conventional imaging findings (Abstract 5501).

PyL PET Tracer May Be Superior to Standard Imaging for Prostate Cancer

May 30th, 2020 - PSMA-targeted 18F-DCFPyL-PET/CT imaging demonstrated excellent diagnostic performance in men with biochemically relapsed prostate cancer in terms of a correct localization rate that far exceeded the criteria to meet the primary end point, according to findings from the phase 3 CONDOR trial.

May 30th, 2020 - Imaging with 18F-DCFPyL-PET/CT outperformed that of standard imaging modalities—such as bone scan, CT, MRI, and FDG PET—in patients with biochemically relapsed prostate cancer in the phase 3 CONDOR trial.

May 29th, 2020 - Imaging with 18F-DCFPyL–PET/CT was found to be diagnostically effective, often guiding a change in treatment plan, in men with biochemically relapsed prostate cancer, according to the results of the phase III CONDOR study presented during the ASCO20 Virtual Scientific Program (Abstract 5501).

Improved Treatment Response Following Magnetic Resonance Imaging–Guided Focused Ultrasound for Lumbar Facet Joint Pain

Magnetic resonance imaging–guided focused ultrasound (MRgFUS) is a noninvasive modality that allows for precise tissue ablation with sparing of surrounding structures. Early reports of the use of MRgFUS for the treatment of facet joint osteoarthritis are promising. We present a case of facet joint pain treated successfully by MRgFUS at our institution. Magnetic resonance imaging–guided focused ...

Cardiovascular Magnetic Resonance Findings in Competitive Athletes Recovering From COVID-19 Infection

Myocarditis is a significant cause of sudden cardiac death in competitive athletes and can occur with normal ventricular function.1 Recent studies have raised concerns of myocardial inflammation after recovery from coronavirus disease 2019 (COVID-19), even in asymptomatic or mildly symptomatic patients.2 Our objective was to investigate the use of cardiac magnetic resonance (CMR) imaging in com...

Flow-metabolism dissociation in the pathogenesis of levodopa-induced dyskinesia

Levodopa-induced dyskinesia (LID) is the most common, disruptive complication of Parkinson’s disease (PD) pharmacotherapy, yet despite decades of research, the changes in regional brain function underlying LID remain largely unknown. We previously found that the cerebral vasomotor and metabolic responses to levodopa are dissociated in PD subjects. Nonetheless, it is unclear whether levodopa-med...

The serotonergic system in Parkinson’s patients with dyskinesia: evidence from imaging studies

The purpose of review is to review the current status of positron emission tomography (PET) molecular imaging of serotonergic system in Parkinson’s patients who experience levodopa-induced (LIDs) and graft-induced dyskinesias (GIDs). PET imaging studies have shown that Parkinson’s disease is characterized by progressive loss of dopaminergic and serotonergic neurons. Parkinson’s patients who exp...

Risk factors of levodopa-induced dyskinesia in Parkinson’s disease: results from the PPMI cohort
NPJ Parkinson's Disease;

Levodopa-induced dyskinesias (LID) negatively impact on the quality of life of patients with Parkinson’s disease (PD). We assessed the risk factors for LID in a cohort of de-novo PD patients enrolled in the Parkinson’s Progression Markers Initiative (PPMI). This retrospective cohort study included all PD patients enrolled in the PPMI cohort. Main outcome was the incidence rate of dyskinesia, de...

Imaging in Parkinson’s disease
Clinical Medicine;

The clinical presentation of Parkinson’s disease (PD) is heterogeneous and overlaps with other conditions, including the parkinsonian variant of multiple system atrophy (MSA-P), progressive supranuclear palsy (PSP) and essential tremor. Imaging of the brain in patients with parkinsonism has the ability to increase the accuracy of differential diagnosis. Magnetic resonance imaging (MRI), single ...

Dopamine Transporter Density in de novo Parkinson's Disease Does Not Relate to the Development of Levodopa-Induced Dyskinesias

In Parkinson’s disease (PD), the onset of levodopa-induced dyskinesias (LIDs) is difficult to predict. This study examines whether dopamine transporter (DAT)-specific SPECT imaging in de novo PD relates to later development of LIDs.

Alcohol Intoxication and Cognition: Implications on Mechanisms and Therapeutic Strategies

Binge alcohol drinking is highly prevalent in young adults and results in 30% deaths per year in young males. Binge alcohol drinking or acute alcohol intoxication is a risk factor for developing alcohol use disorder (AUD). Three FDA approved drugs are currently in use as therapy for AUD; however, all of them have contra-indications and limitations. Structural brain imaging studies in alcoholics...

2019 Update of the American College of Rheumatology/Spondylitis Association of America/...
Arthritis & Rheumatology (Hoboken, N.J.); Ward MM, Deodhar A et. al.

Aug 23rd, 2019 - To update evidence-based recommendations for the treatment of patients with ankylosing spondylitis (AS) and nonradiographic axial spondyloarthritis (SpA). We conducted updated systematic literature reviews for 20 clinical questions on pharmacologic treatment addressed in the 2015 guidelines, and for 26 new questions on pharmacologic treatment, treat-to-target strategy, and use of imaging. New q...

Highlighting COVID-19 Blood Clot Dangers

Based on recent reports that demonstrated a strong association between elevated D-dimer levels and poor prognosis, concerns have risen about thrombotic complications in patients with COVID-19. To address these concerns, the National Institute for Public Health of the Netherlands asked a group of radiology and vascular medicine experts to provide guidance for the imaging workup and treatment of ...

Outcome of epidural blood patch for imaging-negative spontaneous intracranial hypotension.
Cephalalgia : an International Journal of Headache; Choi SY, Seong M et. al.

Feb 6th, 2023 - Spontaneous intracranial hypotension is diagnosed by an abnormal finding in brain MRI, spinal imaging, or lumbar puncture. However, the sensitivity of each test is low. We investigated whether patients with suspected spontaneous intracranial hypotension and negative imaging findings would respond to epidural blood patch. We prospectively recruited patients with new-onset orthostatic headache ad...

Use of clinical scores in young Australian adults for prediction of atherosclerosis in ...
BMC Cardiovascular Disorders; Huynh Q, Venn AJ et. al.

Feb 5th, 2023 - We sought to apply a simple cardiovascular health tool not requiring laboratory tests (the Fuster-BEWAT score, FBS) to predict subclinical atherosclerosis. This study included 2657 young adults (< 40 years of age). In the prognostic group (n = 894, followed for 13 years until aged 40-50 years at follow-up), the primary outcome was presence of carotid plaque measured by carotid ultrasound at fol...

BMC Pulmonary Medicine; Lu L, Peng J et. al.

Feb 5th, 2023 - The role of airway impairment assessed by impulse oscillometry (IOS) in patients with chronic obstructive pulmonary disease (COPD) remains unclear. Therefore, this study aimed to analyze the proportion and clinical characteristics of airway impairment assessed by IOS across COPD severities, and explore whether airway impairment is a subtype of COPD. This study was based on cross-sectional data ...
