Background The purpose of the study was to assess the correlation between peritumoral edema (PE) seen on magnetic resonance imaging (MRI) in breast cancer and the established pathological prognostic factors like tumor histology and molecular subtype, grade, Ki67 index, lymphovascular invasion (LVI) and nodal stage. The breast MRI and pathological d...

Background The purpose of this study was to compare the Image Quality, Contrast Medium Volume, and Radiation dose in renal angiography performed using Turbo Flash mode and dual-energy (DE) mode in the third-generation dual-source dual-energy CT. This prospective observational study was performed on renal donors who underwent CTA imaging as a pre-tr...

Objectives The purpose of our study was to evaluate the virtual monochromatic imaging in detecting hypervascular focal liver lesions in the late arterial phase with third-generation dual-source dual-energy computed tomography and to assess its image quality. Materials and Methods In our study, 80 patients were included. Contrast-enhanced images in...

Purpose: Our study aimed to compare the sensitivity of T2 relaxometry and positron emission tomography - computed tomography (PET/CT) in patients with a history suggestive of mesial temporal lobe epilepsy using video electroencephalography (EEG) as the reference standard. Material and methods: In our study, 35 patients with a history suggestive...

Objectives The aims of our study were to assess the comparability of conventional unenhanced images (CUIs) of hepatopancreaticobiliary system with virtual unenhanced images (VUIs) derived from arterial and portal venous phases acquired in a third-generation, dual-source, dual-energy CT (DECT), and also to assess the best dataset among these VUIs. W...

Purpose: The aim of our study was to compare single-energy (SECT) and dual-energy (DECT) abdominal computed tomography (CT) examinations in matched patient cohorts regarding the differences in effective radiation dose (ERD) and image quality performed in a third-generation dual-source computed tomography (DSCT) scanner. Material and methods: Our...
Article
Purpose: To prospectively estimate the reliability of B-mode ultrasonography and sonoelastography in differentiating benign and malignant cervical lymph nodes with cytological findings as to the reference standard. Materials and methods: A total of 50 patients referred for sonography for enlarged cervical lymph nodes were included in the study....

Urinoma is defined as the extravasation of urine from any part of the urinary collecting system, which causes lipolysis of the surrounding fat, resulting in an encapsulated collection. The most common cause of urinoma is the direct obstruction of the urinary system. The other etiologies include trauma and postinstrumentation/surgery. Parenchymal ca...

Cystic renal lesions are commonly seen on a daily basis in abdominal imaging. Even though most cystic renal lesions are benign simple cysts, complex and multifocal cystic renal diseases are also common with a vast number of differentials. One of the rare mimickers of this condition is renal lymphangiectasia, and the disease can be diagnosed if radi...

Background Acute necrotizing pancreatitis (ANP) is associated with higher mortality and morbidity. We need a method which is accurate in predicting the prognosis, and when applied early in the disease process, can help in closer monitoring and early initiation of treatment for at-risk patients. Objectives The aim of this prospective study was to as...
