Pulmonary embolism (PE) is a preventable cause of morbidity and mortality which needs prompt recognition. Ventilation-perfusion (V/Q) scan is a well-established diagnostic test for evaluation of suspected PE. We report a 32-year-old woman with history of rheumatologic disease and acute dyspnea, who was referred for V/Q scintigraphy. The planar images revealed multiple mismatched defects through...

Introduction: Hyperparathyroidism is presented with increased parathyroid hormone (PTH) secretion due to hyperfunctioning of one or more of the four parathyroid glands. Primary hyperparathyroidism (p-HPT) can be due to parathyroid adenoma, hyperplasia or carcinoma of the parathyroid gland. Secondary hyperparathyroidism (s-HPT) is usually a response to hypocalcaemia and consecut...

An enostosis or bone island is a benign bony lesion that is almost diagnosed based on clinical and radiologic defining characteristics. One of the known diagnostic procedures in the evaluation of enostosis is bone scintigraphy. Generally, we don’t expect to see increased uptake by enostosis in the bone scan. Herein we present a 52-year-old lady who was suffering from chronic low back pain that ...

Bone scan analyses and clinical assessment are used to diagnose unilateral condylar hyperactivity (UCH). This review compares the diagnostic accuracy of planar and SPECT bone scans. Studies diagnosing patients with possible UCH using bone scans, published between 1968 and 2008, were included in this review. Of 15 articles that met the inclusion criteria, 7 presented results in sufficient detail...

Results: In SPECT study visual analysis correlated extremely well with clinical features. Comparison of patient SPECT data with normal population showed significant hypoperfusion of lower limbs in terms of counts (P-value <0.001). Follow up of patients (N=12) showed significant improvement of muscle perfusion in nine patients while three patients showed no improvement. Comparison of follow up p...

introduction: renal length measurement is an important diagnostic clue in several urinary tract abnormalities. although ultra sonography is the most frequent used modality for renal size estimation, renal diameter assessment by 99mtc-dmsa scintigraphy is of great value. by now, pointing to the renal size in the 99mtc-dmsa scintigraphy report has not been recommended by guidelines. if the validi...
