Introduction/Background: Sebaceous lymphadenoma is a rare parotid gland neoplasm. Up to now, there have been several studies that have discussed the imaging manifestations of salivary sebaceous lymphadenoma. In this paper, we have reported a case of multiple parotid sebaceous lymphadenoma demonstrated by ultrasound, CT scan, and MRI examinations, including diffusion-weighted imaging. To the best of our kn Read More

Introduction: Venous air embolism (VAE) consists of air entering vascular structures due to a pressure gradient generated during medical-surgical procedures. Most cases of VAE are iatrogenic. Case Reports: Three hospitalised patients aged 23 to 86 years underwent venous air embolism (VAE) in the right heart system after performing CTPA. One of the patients died from a complication of venous thromboembolic disease (PE, c Read More

Over the recent years, magnetoresistive (MR) sensors in biosensing technologies have played a pivotal role in detecting and quantifying biomarkers. The article highly focuses on the potential implications of tunneling magnetoresistance (TMR), giant magnetoresistance (GMR), anisotropic magnetoresistance (AMR), and hybrid MR sensors over conventional prototypes. The study mainly elaborates on the sensor Read More

Background The prognosis of postoperative tumor deposits (TDs) is worse than positive lymph node metastases alone. Objective To detect TDs by using multiplanar high-resolution T2-weighted imaging (HRT2WI). Material and Methods This retrospective study enrolled 130 patients with locally advanced rectal cancer (LARC). Using pathology-proven tumor deposits (pTDs) as the gold standard, all patients were divided into the pT Read More

Background The jaws can be affected by several lesions that manifest in the oral cavity, but little is known about non-odontogenic benign and malignant lesions and their radiological findings. Introduction Our aim was to discuss the imaging findings of non-odontogenic jaw lesions to help the surgeon in the diagnosis and formulating a differential diagnosis for this vast spectrum of jaw lesions with overlapping clinical and im Read More

Objective The present study aimed to analyze mammography and ultrasonography (US) manifestations of sclerosing lymphocytic lobulitis (SLL) of the breast. Methods A total of 8 pathologically confirmed SLL lesions from seven women (with one patient having bilateral breast lesions) were included in the study. All patients underwent preoperative mammography and US examinations. The findings from both modalities were Read More

Background Ganglioglioma is a rare, slowly proliferating mixed glioneuronal tumor, with the highest incidence observed in children and young adults, but it can also occur in adults. Objective This study aimed to compare the imaging characteristics of ganglioglioma in children/adolescents and adults to facilitate radiographic diagnosis. Methods In this retrospective study, a total of 32 patients were included and divided into t Read More

Aims This study aimed to develop a method for predicting short-term outcomes of lung cancer patients treated with intensity-modulated radiotherapy (IMRT) using radiomic features detected through computed tomography images. Methods A prediction model was developed based on a dataset of radiomic features obtained from 132 patients with lung cancer receiving IMRT. Dimension reduction was performed for t Read More

The testis is a richly vascularized organ supplied by low-flow thin caliber vessels that are only partially detected by traditional Doppler systems, such as color and power Doppler. However, in the vascular representation, these techniques determine, albeit to different extents, a cut of the weak vessels due to the necessary application of wall filters that cut the disturbing frequencies responsible for artifacts generated by pulsatio Read More

Objective The objective of this study was to investigate the diagnostic power of apparent diffusion coefficient/coefficient of variance (ADCcV) as well as ADC parameters formed based on magnetic resonance images (MRI) in the distinction of molecular breast cancer subtypes. Methods The study involved 205 patients who had breast cancer at stages 1-3. Estrogen receptor (EsR), progesterone receptor (PrR), human epidermal gro Read More

Background Few studies have focused on the changes in human brain function activities caused by reading Chinese characters with different intelligibility and whether it can reflect the understanding and cognitive ability of the human brain. Objective Task-fMRI based on Chinese character reading tasks with different intelligibility was used to explore activated brain regions and their cognitive changes. Methods Volunteers we Read More

Introduction Among all cancer forms, gastrointestinal (GI) cancer is the most serious condition that spreads quickly and requires early detection. GI disorders claim the lives of up to nearly two million people worldwide. To lower the mortality rate from GI cancer, early detection is essential. Methods For the identification of GI illnesses, such as polyps, stomach ulcers, and bleeding, endoscopy is the gold standard in the medic Read More

Objective To analyze the efficacy of microwave ablation (MWA) guided by computed tomography (CT) and 1.5T magnetic resonance (MR) in the treatment of VX2 para-vascular liver tumor model in rabbits. Materials and Methods Sixty para-vascular VX2 liver tumor models in rabbits were randomly divided into CT-guided microwave ablation group (CT group, n=35) and MR-guided microwave ablation group (MR group, n=3 Read More

Objective Extraprostatic extension (EPE) serves as a crucial marker of prostate cancer aggressiveness and independently predicts the likelihood of biochemical recurrence (BCR), exhibiting a strong correlation with the histologic severity of EPE. Therefore, this study aimed to investigate the probability of EPE along the zonal level of the prostate by measuring tumor contact length (TCL) using multiparametric magnetic resona Read More

Background The composition of kidney stones is related to the hardness of the stones. Knowing the composition of the stones before surgery can help plan the laser power and operation time of percutaneous nephroscopic surgery. Moreover, patients can be treated with medications if the kidney stone is compounded by uric acid before treatment, which can relieve the patients of the pain of surgery. However, although the Read More

Introduction Budd-Chari syndrome (BCS) is a rare condition defined by the obstruction of hepatic venous outflow. BCS is a relatively infrequent cause of acute liver failure (ALF), accounting for less than 1% of cases. Treatment for acute BCS consists of a stepwise approach, requiring anticoagulation, angioplasty, transjugular intrahepatic portosystemic shunt (TIPS), and liver transplantation. Case Report We present the Read More
