Background: Lung cancer has the highest mortality rate among cancers. Radiation therapy (RT) is one of the most effective therapies for lung cancer. The correct segmentation of lung tumors (LTs) and organs at risk (OARs) is the cornerstone of successful RT. Methods: We searched four databases for relevant material published in the last 10 years: Web of Science, PubMed, Science Direct, and Google Scholar. The advanc Read More

Background: It is still uncertain to determine the exact diagnostic accuracy of MRI for medial meniscus (MM) tear, lateral meniscus (LM) tear and MM posterior root tear (MMPRT) at different magnetic field intensities (MFIs), different sequences and different publication dates. This study aimed to identify the diagnostic performance of MRI for different meniscus lesions at different MFIs, different sequences and different publicati Read More

Background: Few studies comprehensively compared the performance of transient elastography (TE) and two-dimensional shear wave elastography(2D-SWE) to diagnose the stage of liver fibrosis in children and adolescents. We assessed the diagnostic performance of these non-invasive imaging techniques from published studies. Methods: To evaluate the diagnostic performance of TE and 2D-SWE, we searched t Read More

Objective: To explore the MRI T2 fluid-attenuated inversion recovery (FLAIR) vascular hyperintensities (FVH) combined with diffusion-weighted imaging (DWI) Alberta Stroke Program Early CT Score (ASPECTS) in predicting the prognosis of acute cerebral infarction (ACI) with endovascular treatment. Methods: The patients with ACI in the anterior circulation who underwent endovascular treatment from June 2016 to Decem Read More

Objective: The aim of this study is to determine the clinical and laboratory parameters which may be suggestive of or even pathognomonic for primary epiploic appendagitis (PEA) and to discuss the diagnostic efficacy of ultrasound (US) compared to computed tomography (CT) in patients with PEA. Materials and Methods: For this retrospective study, 92 patients diagnosed with PEA using US, CT or both modalities were inclu Read More

Purpose: To evaluate the diagnostic performance of three-dimensional volume of interest (3D-VOI) perfusion quantitative parameters using CS-VIBE DCE-MRI and investigate the relationship of the prognostic factors. Materials and Methods: The volumetric perfusion quantitative parameters of Ktrans, Kep, Ve, Vp, of 124 pathologically proven breast masses in 93 patients were obtained using the two-compartment extended Toft Read More

Objectives: The position of the inferior alveolar canal (IAC) and its course in the mandible is crucial to prevent complications in oral surgical procedures. Therefore, the present study aims to predict the course of IAC using landmarks specific to the mandible and to correlate with cone-beam computed tomography images. Methods: On the included panoramic radiographs (n=529), the closest point of the IAC to the infer Read More

Objective: To compare the efficacy and safety of 1.5 T MRI and CT-guided VX2 hepatic para-vascular tumor model in rabbits. Materials and Methods: Sixty New Zealand white rabbits were randomly and equally divided into MRI-guided group (n=30) and CT-guided group (n=30). Rabbit VX2 tumor fragments were implanted beside the rabbit hepatic great vessels under MRI and CT guidance in the MRI and CT group to ev Read More

Objective: The study aimed to analyze computed tomography and magnetic resonance imaging features of patients with solitary extramedullary plasmacytoma. Methods: Ten cases with solitary extramedullary plasmacytoma were included in this study. CT and MRI features of solitary extramedullary plasmacytoma were retrospectively analyzed. Results: This study included both males (n = 8) and females (n = 2), with Read More

Background: Teratoma is a true neoplasm composed of a number of different types of tissue derived from the three germinal layers but rarely occurs in the middle ear (ME). The features of middle ear teratomas (MET) have not been well described. Objective: The objective of this study is to explore the clinical and imaging features of MET, and report 2 rare cases of MET with ear malformation that have never been reported. Read More

Objective: Shear wave elastography imaging (SWE) is a non-invasive US technique that has been developed to provide quantitative information about tissue elasticity. This technique might be useful in the identification of vascular risk factors. Arterial wall thickness and inner diameter vary with age and disease, which may impact shear wave propagation. The effect of arterial geometry on SWE has not yet been thoroughly i Read More

Background: Diagnostic accuracy of double-contrast barium enema (DCBE) depends upon the barium sulfate coating efficiency in the colon. Objective: To evaluate effects of three laxatives on barium sulfate coating efficiency in the large intestine, sigmoid colon, and hepatic flexure in DCBE. Methods. This retrospective study included patients receiving DCBE after pre-procedure cleansing with Dulcolax® with castor oil ( Read More

Introduction: Chondrosarcomas are primary malignant bone tumor that rarely occurs in the head and neck region. Squash cytology of skull base neoplasm shows atypical chondrocytes and myxoid stroma, which suggests many possibilities like chordoma, chordoid glioma, chordoid meningioma and chondrosarcoma. Isocitrate dehydrogenase gene (IDH) mutations have been reported in 50% to 60% of the head and Read More

Background: Pineal region solitary fibrous tumors (SFT) incorporate a histologic spectrum of rarely metastasizing mesenchymal neoplasms that include tumors formerly classified as hemangiopericytoma. Case Report: Here, we describe a rare case of SFT of the pineal region in a 25-year-old man with a literature review. After the first surgery, the tumor reappeared as a local low-grade recurrence, followed by metastasis to th Read More
