Abstract:
In 2 high-risk prostate cancer patients, PET scans revealed focally increased Ga-prostate-specific membrane antigen uptake in the distal esophagus. Both patients had hiatus herniation on gastroscopy, and esophageal biopsies revealed acute and chronic inflammation in both patients and a benign hyperplastic polyp in one of the patients. Recently, reports have demonstrated that inflammation can cause false-positive findings on Ga-prostate-specific membrane antigen PET/CT, and these cases present this phenomenon in the esophagus as well.

Radiological Investigation III: Pulmonary Angiogram and PET Scan
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Esophageal Strictures-I: Introduction
Etiology
The primary cause of esophageal strictures is long-standing gastroesophageal reflux disease (GERD), accounting for about 70 to 80% of adult cases. Chronic acid reflux can lead to injury and scarring of the esophageal lining, culminating in...
