Computed Tomography Findings Affecting the Decision of Sternotomy in Substernal Goiter.

Objectives: Although thyroidectomy is completed with a cervical incision in most patients with substernal goiter (SG), sternotomies may be required occasionally. The purpose of this study is to examine computed tomography (CT) findings that may predict the need for sternotomy in SG surgery.

Methods: Neck-thoracic CT images of patients who underwent total thyroidectomy with the diagnosis of SG between 2013 and 2022 were retrospectively examined.

Differentiating renal cell carcinoma and oncocytoma with volumetric MRI histogram analysis.

Objective: In this study, the utility of histogram parameters derived from diffusion-weighted imaging for differentiate renal cell carcinoma (RCC) from oncocytoma was investigated.

Methods: This research tracked 126 individuals who were diagnosed with RCC and oncocytoma through histopathological analysis, using magnetic resonance imaging (MRI) assessments from 2015 to 2023. We observed various attributes of these patients, including demographic details, surgical records, pre-surgery MRI results, MRI apparent diffusion coefficient (ADC) histogram analysis, and post-surgery histopathological outcomes.

Analysis of Pancreatobiliary and Intestinal Type Periampullary Carcinomas Using Volumetric Apparent Diffusion Coefficient Histograms.

Rationale And Objectives: Magnetic resonance imaging plays an important role in the evaluation of patients with known or suspected periampullary masses. The utilization of volumetric apparent diffusion coefficient (ADC) histogram evaluation for the entire lesion eradicates the potential for subjectivity in the region of interest placement, thus guaranteeing the accuracy of computation and repeatability.

Purpose: To investigate the value of volumetric ADC histogram analysis in the differentiation of intestinal-type (IPAC) and pancreatobiliary-type periampullary adenocarcinomas (PPAC).

Predictive value of sphericity index and other multidetector computed tomography findings in perforated acute appendicitis.

Background: Early radiological prediction and diagnosis of perforated acute appendicitis remain controversial. In the current study, it was aimed to examine the predictive value of multidetector computed tomography (MDCT) findings in perforated acute appendicitis.

Methods: The patients (n=542) who underwent appendectomy between January 2019 and December 2021 were retrospectively evaluated.

The Effectiveness of Volumetric MRI Histogram Analysis in Renal Cell Carcinoma.

Rationale And Objectives: This study investigated the utility of histogram parameters derived from diffusion-weighted imaging (DWI) for evaluating renal cell carcinoma (RCC) grading prior to surgery.

Materials And Methods: This retrospective study included 88 patients who were histopathologically diagnosed with RCC and underwent magnetic resonance imaging (MRI) examinations. The patients were divided into two groups as well-differentiated (Group 1) and poorly differentiated (Group 2).

Evaluation of Imaging Findings of Pancreatobiliary and Intestinal Type Periampullary Carcinomas with 3.0T MRI.

Rationale And Objectives: The aim of this study was to differentiate pancreatobiliary and intestinal type periampullary carcinomas using dynamic contrast MRI and MRCP (Magnetic Resonance Cholangiopancreatography) with diffusion-weighted imaging (DWI) MATERIALS AND METHODS: MRI and MRCP images of 70 patients with pathologically proven periampullary adenocarcinoma were included. MRCP image features, extra-ampullary features, enhancement patterns, and apparent diffusion coefficient (ADC) values derived from b-values of 1000 s/mm² were evaluated by two radiologists independently. The interclass correlation coefficient (ICC) or Cohen's kappa statistic was used to evaluate the interobserver agreement.

Gastric perforation: An unusual complication after esophageal intubation.

Gastric perforation secondary to accidental esophageal intubation is a very rare mortal complication with only a few cases reported in the literature. In the management of this fatal complication, the early diagnosis and rapid surgical intervention are critical. In this case report, we present our experience with an unusual case, who required intubation in the intensive care unit due to acute hypoxemia and subsequently developed gastric perforation.

A Comparative Olfactory MRI, DTI and fMRI Study of COVID-19 Related Anosmia and Post Viral Olfactory Dysfunction.

Rationale And Objective: To evaluate how COVID-19 anosmia imaging findings resembled and differed from postinfectious olfactory dysfunction (OD).

Material And Methods: A total of 31 patients presenting with persistent COVID-19 related OD and 97 patients with post-infectious OD were included. Olfactory bulb MRI, DTI and olfactory fMRI findings in both groups were retrospectively assessed.

Neutrophil oxidative metabolism in Down syndrome patients with congenital heart defects.

Down syndrome (DS) occurs when an individual has three, rather than two, copies of the 21st chromosome. Cytosolic superoxide dismutase (SOD-1) is encoded by a gene on chromosome 21 and thus, SOD-1 activity is elevated in patients with DS. Forty percent of all cases with DS are associated with congenital heart defects (CHD).
