Patients diagnosed with DVT in the acute-subacute stage (<4 week) with total thrombosis in lower extremity were included in this prospective study.

Radiological Evidence of Testicular Damage in Severe Acute Respiratory Syndrome Coronavirus 2 Infection: A Sonoelastography's Potential Role.

This preliminary study aimed to evaluate the possible damage to the male reproductive system that the severe acute respiratory syndrome coronavirus 2 virus causes by quantitatively measuring and comparing the tissue stiffness of the testis and epididymis with acoustic radiation force impulse sonoelastography in patients who have COVID-19 with a healthy control group. This prospective study was conducted between February and July 2021 with 65 cases. We used sonoelastography to evaluate male patients 18 years or older, who had applied to the urology clinic with nontesticular complaints, and were found to not have any underlying testicular pathology after a clinical-laboratory evaluation.

The Efficiency of Diffusion-weighted Magnetic Resonance Imaging in the Differentiation of Malign and Benign Cavitary Lung Lesions.

Purpose: The present study investigates the diagnostic efficiency of apparent diffusion coefficient (ADC) values in differentiating between malignant and benign cavitary lesions on diffusion-weighted magnetic resonance imaging (DWI).

Materials And Methods: This prospective study included 45 consecutive patients identified with a cavitary lung lesion with a wall thickness of ≥5 mm on thoracic computed tomography in our clinic between 2020 and 2022, and who underwent thoracic DWI within 1 week of their original computed tomography. ADC measurements were made on DWI by drawing a region of interest manually from the cavity wall, away from the lung parenchyma in the axial section where the lesion was best demonstrated.

Methods: This retrospective study was conducted with 116 patients diagnosed with CD, 14 CD patients recovering with treatment, and 35 control patients with non-CD. All patients had CT examinations and histopathological diagnoses.

Clinical Impacts of Juxtapapillary Duodenal Diverticulum Detected on Computed Tomography.

Background: Diverticula are commonly observed in the duodenum. Duodenal Diverticulum (DD) usually does not give symptoms throughout life and is diagnosed by coincidence. However, it may present with different symptoms in patients.

Radiological evaluation of response to treatment in hepatobiliary fascioliasis.

Purpose: In this study, we aimed to evaluate the computed tomography (CT) findings of Fasciola hepatica infestations on initial and follow-up imagings after treatment, and also to describe the role of CT during diagnosis.

Methods: In this retrospective study, patients with a diagnosis of fascioliasis by clinical and laboratory examination who underwent initial and follow-up contrast-enhanced abdominal CT scans after treatment (a single oral dose of 10mg/kg Triclabendazole) were included. The CT scans were evaluated regarding liver and spleen sizes, portal and splenic vein diameters, involved hepatic segment numbers and involvement patterns, the presence of focal perihepatic hyperdensity, gallbladder wall thickening, dilatation of the intrahepatic biliary tract, periportal-right subdiaphragmatic lymphadenopathy, hepatic subcapsular and intra-abdominal bleeding, and perihepatic/intraabdominal free fluid.

Evaluation of celiac disease with uniphasic and multiphasic dynamic MDCT imaging.

Purpose: An analysis of dynamic contrast MRI has been shown to provide valuable information about disease activity in Crohn's disease and Celiac disease (CD). However, there are no reports of dynamic multi-detector computer tomography use in patients with CD. The aim of this study is to determine and compare the perfusion dynamics of the patients treated with control subjects and the perfusion dynamics in patients with untreated CD, using dynamic contrast in MDCT and compare studying contrast dynamics in Marsh types as well.

Anterior Cerebral Artery and Anterior Communicating Artery Variations: Assessment with Magnetic Resonance Angiography.

Background: Although anterior cerebral artery (ACA) and anterior communicating artery (AcomA) variations have been frequently investigated by contrast-enhanced angiography, the number of studies performed with magnetic resonance angiography is quite low. Our aim in this study is to investigate ACA and AcomA variations with time of flight magnetic resonance angiography (TOF MRA).

Methods: Source and maximum intensity projection images of 581 adult patients (273 males, 308 females) who were scanned for intracranial arteries with the TOF MRA method were retrospectively analyzed.

Contrast enhanced computed tomography findings of persistent truncus arteriosus; A rare congenital heart disease.

Persistent Truncus Arteriosus is a cyanotic congenital heart anomaly in which a single trunk supplies both the pulmonary and systemic circulation, instead of a separate aorta and a pulmonary trunk. It is usually classified as a conotruncal anomaly. Due to parallel fetal circulation, truncus arteriosus does not cause any haemodynamic problem in utero.
