Effectiveness of diffusion-weighted magnetic resonance imaging (DW-MRI) in the differentiation of thyroid nodules.

Background: The aim was to investigate which of two different b values (b 500 s/mm² and b 800 s/mm²) are more effective in the differentiation of benign-malignant nodules using Diffusion-Weighted Magnetic Resonance Imaging (DW-MRI).

Materials And Methods: Patients presenting with a preoperative diagnosis of nodular goiter or multinodular goiter were included in this study. These patients underwent neck MRI examinations, and their cases were analyzed retrospectively.

A retrospective multicenter evaluation of cutaneous melanomas in Turkey.

Background: We defined melanoma distribution in a large series of Turkish patients and evaluated the prognostic parameters of melanomas.

Materials And Methods: A total of 1574 patients' data was retrospectively collected at 18 centers in Turkey. Demographic characteristics were questioned and noted.

An unusual association of Goldenhar syndrome.

Goldenhar syndrome is well known for its classical triad of epibulbar dermoids or lipodermoids, auricular appendages and pretragal fistulas. Here we report a case of Goldenhar syndrome with an unusual association of a fibroepithelial polyp attached to a limbal dermoid. A case of Goldenhar syndrome in a 5-month-old male infant presented with the features of a fibroepithelial polyp attached to a limbal dermoid, right-sided polydactylia with hypoplastic thumb, and accessory preauricular appendages on the left side.

Perfusion CT evaluation in experimentally induced testicular torsion.

Introduction: In this study, we define the characteristics of perfusion computed tomography (CT) in an experimental model of testicular torsion.

Methods: Twenty male Sprague-Dawley rats were included for the study. Torsion was applied to 10 rats and perfusion CT was performed in the first hour to evaluate the following perfusion parameters: blood flow (BF), blood volume (BV) and time to peak (TTP) values.
