Methods and utility of quantitative brainstem measurements in progressive supranuclear palsy versus Parkinson's disease in a routine clinical setting.

Clin Park Relat Disord 2020 14;3:100033. Epub 2020 Jan 14.

Cleveland Clinic Imaging Institute, 9500 Euclid Ave, Cleveland, OH 44195, United States of America.

Background And Purpose: The clinical diagnosis of progressive supranuclear palsy can be challenging, as the clinical presentation overlaps with that of Parkinson's disease and multiple system atrophy. We sought to examine the practical utility of radiologic markers of progressive supranuclear palsy by investigating whether these markers could distinguish between patients with progressive supranuclear palsy-Richardson syndrome (PSP-RS) and those with Parkinson's disease based on imaging obtained in a typical clinical setting, not in a prospective research environment.

Materials And Methods: This retrospective study included 13 patients with PSP-RS and 13 patients with Parkinson's disease who were followed for either condition at our institution at the time of the study and who had MRI records available. Read More

The effect that pathologic and radiologic interpretation of invasive and non-invasive areas in lung adenocarcinoma has on T-stage and treatment.

Ann Diagn Pathol 2021 Jul 20;54:151799. Epub 2021 Jul 20.

Department of Pathology and Laboratory Medicine Rhode Island Hospital, The Warren Alpert School of Medicine, Brown University, United States of America. Electronic address:

Lung adenocarcinoma is currently staged based on invasive tumor size, excluding areas of lepidic (in situ) growth. Invasive tumor size may be determined by pathologic assessment of a surgical specimen or radiographic assessment on computerized tomography (CT) scan. When invasive tumor size is the primary stage determinate, radiographic-pathologic discordance or discordant interpretation among pathologists may alter tumor stage and treatment. Read More
