Latent polyglandular autoimmune syndrome type 2 case diagnosed during a shock manifestation.

There are many types of polyglandular autoimmune syndrome (PAS). PAS type 2 is the most common type among adults. For PAS type 2 (PAS-2) diagnosis, detection of Addison's disease with autoimmune thyroid disease and/or type 1 diabetes mellitus are required.

Cardiac blood pool activity on postablation radioiodine imaging.

Objective: There are reports on physiologic and pathologic mediastinal uptake on radioiodine imaging in patients with thyroid carcinoma. The most commonly reported physiologic causes of mediastinal uptake are esophageal retention of salivary secretion and uptake by hyperplastic or normal thymus gland. In this study, we evaluated physiologic cardiac blood pool (CBP) activity and its associated findings on radioiodine imaging.

Comparison of standardized uptake values obtained from two- and three-dimensional modes of fluorine-18 fluorodeoxyglucose PET-CT in oncological cases.

Purpose: We investigated the usability of standardized uptake values (SUV) obtained from both two- and three-dimensional (2D and 3D) positron-emission tomography and computed tomography (PET-CT) imaging, and compared the images obtained from these techniques in terms of image quality, lesion detectability, and the presence of artifacts.

Materials And Methods: Image data from 100 patients, who had undergone two PET imagings obtained in 2D and 3D mode after a low dose CT, were evaluated prospectively. Subjective analysis of 2D and 3D images was performed by two readers evaluating the following criteria: overall image quality, detectability of each identified lesion, and the presence of artifacts.

The biodistribution of radioiodine on posttherapy iodine-131 scans in thyroid cancer patients with chronic renal failure.

Objectives: Owing to ineffective iodine removal, radioiodine dose reduction was recommended in thyroid cancer patients with chronic renal failure. In this study, the radioiodine biodistribution pattern on posttherapy scans in patients with normal renal function and those with chronic renal failure is outlined.

Methods: This study included 10 thyroid cancer patients with chronic renal failure (five females, five males; mean age: 43+/-12.
