Radiological assessments of the small and large bowel are essential in daily clinical practice. Over X-ray plain films and ultrasound, cross-sectional techniques are considered the most comprehensive imaging modalities. "Cross-sectional techniques" refers to CT and MRI, as stated in the following sentence. In fact, computed tomography and magnetic resonance imaging take great advantage of the three-dimensional app Read More

Ultrasound is one of the most widely utilized imaging tools in clinical practice with the advantages of noninvasive nature and ease of use. However, ultrasound examinations have low reproducibility and considerable heterogeneity due to the variability of operators, scanners, and patients. Artificial Intelligence (AI)-assisted ultrasound has advanced in recent years, bringing it closer to routine clinical use. The combination of Read More

Objectives: This study aims to investigate the efficacy of abbreviated breast magnetic resonance imaging (MRI) in neoadjuvant chemotherapy (NAC) response evaluation. Methods: MR images of 50 locally advanced breast cancer patients who underwent standard protocol (SP) breast MRI before and after NAC were re-evaluated retrospectively. Abbreviated protocol (AP) was obtained by extracting images from SP and then Read More

Background: The prediction of pathological responses for locally advanced rectal cancer using magnetic resonance imaging (MRI) after neoadjuvant chemoradiotherapy (CRT) is a challenging task for radiologists, as residual tumor cells can be mistaken for fibrosis. Texture analysis of MR images has been proposed to understand the underlying pathology. Objective: This study aimed to assess the responses of lesions to Read More

Background and Objective: Differentiating non-small cell lung cancer (NSCLC) from small cell lung cancer (SCLC) remains a substantial challenge. This study aimed at evaluating the performance of dual-layer spectral detector CT (DLCT) in differentiating NSCLC from SCLC. Methods: Spectral images of 247 cancer patients confirmed by pathology were retrospectively analyzed in both the arterial phase (AP) and the venous pha Read More

Background: Pancreatic cancer is mostly diagnosed in advanced stages, and treatment results are not satisfactory. L3 skeletal muscle index (SMI) has emerged as a prognostic factor in pancreatic cancer patients. We aimed to assess the association between sarcopenia and overall survival in patients with pancreatic cancer in this study. Methods: Patients who were admitted to the Department of Oncology between March 2012 Read More

Background: Arterial stiffness is an important biomarker for cardiovascular disease. Shear wave elastography (SWE) provides quantitative estimates of tissue stiffness. Objective: This study aimed to provide reference values for arterial wall, assessing the suitability of SWE to quantify elasticity of the common carotid artery (CCA) and evaluating inter-and intra-observer reproducibility. Methods: A Supersonic Aixplorer ult Read More

Objective: The objective of this study is to analyze the clinical and imaging features of desmoplastic fibroma of bone (DFB) for correct diagnosis. Materials and Methods: Twenty patients with DFB confirmed by pathology were enrolled, and the imaging presentations were analyzed. Among 20 patients, plain X-ray was performed in all patients, computed tomography (CT) was performed in 12, and magnetic resonance imaging ( Read More

Background: We aimed to differentiate Glioblastoma Multiforme (GBM) from benign lesions like Developmental Venous Anomaly (DVA) and Cavernous Malformation (CM) by Dynamic Contrast-Enhanced MR Perfusion (DCE-MRP) markers such as Ktrans, Ve, Kep, and IAUC. Methods: We retrospectively evaluated 20 patients; 10 GBM as the malignant group, 5 CM and 5 DVA as the benign group. Ktrans, Kep, Ve, and IAUC Read More

Background: The rate of autoimmune thyroiditis in children with celiac disease (CD) is high relative to the normal population. Since the majority of these patients are also euthyroid, thyroid imaging methods are gaining significance in diagnosis and follow-up. This study examines the effectiveness of thyroid ultrasonography (US) and thyroid shear wave elastography (SWE) in diagnosing thyroid disease in children with Read More

Background: Cross-sectional imaging findings of portal vein calcification were found to be an indicator of portal vein thrombosis. Calcification of the portal vein and its tributaries in portal hypertension is an uncommon finding and the mechanical stress due to long-standing portal hypertension on the vessel wall is considered leading to sclerosis and calcification in the intima and media of the vessel wall. Intra-splenic vascular calcifi Read More

Background: Foreign bodies in the upper aerodigestive tract represent an uncommon cause of visits to emergency departments. In the majority of cases, foreign bodies do not go beyond the pharynx. They cause dyspnoea or pneumonia if they reach the tracheobronchial tree. If ingested, they will pass spontaneously through the gastrointestinal canal in the majority of cases. Nevertheless, especially in the case of sharp-pointed Read More

Background: Sinonasal cavernous hemangioma is rare. To date, fewer than 20 cases have been reported in the literature; however, they may be a source of recurrent epistaxis and masquerade of a hemorrhagic mass on CT and MRI. Case Report: A 68-year-old woman was presented with recurrent epistaxis and progressive right malar fullness. On rhinoscopy, a bulge lesion was observed with multifocal hemorrhagic and fri Read More

Introduction: Uterine tumors resembling ovarian sex cord tumors (UTROSCTs) are rare neoplasms with unknown etiology. This type of tumor has low malignant potential and mostly manifests as a benign clinical course. Materials and Methods: This article analyzes the case data, clinical manifestations, and histopathological characteristics of two cases of UTROSCT, and reviews the relevant literature. The diagnosis of UTR Read More
