Differentiation of malignant from benign pancreatic mass by Tl-201 abdominal SPECT.

The aim of the present study was to evaluate the ability of Tl-201 abdominal SPECT to differentiate between chronic focal pancreatitis and pancreatic malignancy. Seventeen patients (12 men, 5 women; mean age, 56 years; 9 pancreatic cancer, 8 chronic pancreatitis) with pancreatic mass were prospectively investigated with Tl-201 abdominal SPECT. In all patients, CT and/or US could not clarify the...

TL-201 Scanning and in Differentiating Malignant from Benign Masses of Breast

Physical examination and mammography are currently the only proven and reliable methods of early detection of breast cancer. Although, both procedures are highly sensitive, their limited specificity often requires surgical biopsy in order to differentiate between malignant and benign lesions.Palpable mass abnormalities of breast are often difficult to evaluate mammographically, especially in pa...

Differentiation of benign and malignant breast lesions by apparent diffusion coefficient value in mass and non-mass lesions

Background: Diffusion-weighted imaging (DWI) is one of methods in evaluation of breast lesions. We aimed to investigate the apparent diffusion coefficient (ADC) values in breast tumors and their accuracy in differentiating benign versus malignant lesions. Methods: In this cross-sectional study, 72 patients with 88 breast lesions were investigated by 1.5-T breast MRI from 2015 to 2017 in Athari...

Dose Nitroglycerine enhance detection of viable myocardium by Tl-201 SPECT? [Persian]

It is suggested that sublingual nitroglycerine can improve the ability of T1-201 for detection of viable myocardium. Methods and Results: In a randomized, double blind study, 50 patients who had fixed defects on stress-redistribution scan, were randomized into two groups. In group I, patients received 0.4-0.8 mg sublingual nitroglycerine, before T1-201 reinjection. In group II, reinjectio...
