Bone metastases are a common source of malignancy in the skeleton and occur much more often than primary bone cancer. Several works were being performed to identify early markers for bone metastasis and novel drug targets to improve patients' quality of life. As some concerns exist with the [18F]sodiumfluoridein positron emission tomography (PET) bone imaging, there has been an increase in the number of targete Read More

Background: Magnetic Resonance Imaging (MRI) is frequently employed for the assessment of therapy in head and neck squamous cell carcinoma patients. Nonetheless, this technique has its limitations, the most apparent being the inability to differentiate between after therapy effects and the reoccurrence of tumor cells. Objective: This review was carried out to demonstrate the role of operative MRI in the treatment of head a Read More

Background: Schizotypal Personality Disorder (SPD) is a cluster A personality disorder affecting 1.0% of the general population, characterised by disturbances in cognition and reality testing dimensions, affected regulation, and interpersonal function. SPD shares similar but attenuated phenomenological, genetic, and neurobiological abnormalities with Schizophrenia (SCZ) and is described as part of schizophrenia spectr Read More

Background: An outbreak of coronavirus disease 2019 (COVID-19) has occurred worldwide. However, the small-airway disease in patients with COVID-19 has not been explored. Aim: This study aimed to explore the small-airway disease in patients with COVID-19 using inspiratory and expiratory chest high-resolution computed tomography (CT). Methods: This multicenter study included 108 patients with COVID-19. The Read More

Objective: The study aimed to investigate the relationship between the ratio of lymph node attenuation to primary lesion attenuation on contrast-enhanced CT and the PET/CT standard uptake value (SUVmax) in head and neck squamous cell cancer (HNSCC). Methods: Volunteers with advanced-stage, histopathologically proven HNSCC, indicated to have radiotherapy/chemoradiotherapy, were evaluated for CT and PET/ Read More

Background: Though imaging manifestations of COVID-19 and other types of viral pneumonia are similar, their clinical treatment methods differ. Accurate, non-invasive diagnostic methods using CT imaging can help develop an optimal therapeutic regimen for both conditions. Objective: To compare the initial CT imaging features in COVID-19 with those in other types of viral pneumonia. Methods: Clinical and imaging data of Read More

Background and Aims: Coronavirus Disease 2019 (COVID-19) pandemic has become a global health issue. This study aimed to explore the clinical characteristics and CT imaging features of patients with COVID-19 on admission. Methods: Consecutive patients with laboratory-confirmed COVID-19 were retrospectively recruited to this study from January 2020 to March 2020. According to the disease severity status on admission, Read More

Background: In recent years, there has been a massive increase in the number of people suffering from psoriasis. For proper psoriasis diagnosis, psoriasis lesion segmentation is a prerequisite for quantifying the severity of this disease. However, segmentation of psoriatic lesions cannot be evaluated just by visual inspection as they exhibit inter and intra variability among the severity classes. Most of the approaches currently Read More

Background: Ultrasonography is a diagnostic resource that serves as a complement in the evaluation of patients with carpal tunnel syndrome. The correlation of ultrasonography findings with nerve conduction studies can serve to classify new phenotypes and to evaluate therapeutic responses. Objectives: To determine the diagnostic sensitivity of ultrasound, the correlation between the diameter of the nerve (CSA) against the m Read More

Background: The aetiology of anterior knee pain is multifactorial, and any patellofemoral structure can be the cause of the symptoms. Introduction: For the last decades, the suprapatellar fat pad is studied as a potential cause of anterior knee pain. Since the results in the literature are contradictory, in this study, we tried to reevaluate the role of the suprapatellar fat pad in the development of anterior knee pain. Metho Read More

Purpose: Kidney, Ureter, and Bladder radiography (KUB) has frequently been used in suspected urolithiasis, but its performance is known to be lower than that of Computed Tomography (CT). This study aimed to investigate the diagnostic performance of digitally KUB in the detection of ureteral stones. Materials and Methods: Thirty patients who underwent digital KUB and CT were included in this retrospective study. The Read More

Background: Portal vein velocity (PVV) has shown a reasonable correlation with the presence of portal hypertension in patients with cirrhosis. This study aims to evaluate the value of PVV for diagnosing clinically significant portal hypertension (CSPH) and predicting the risk of variceal hemorrhage (VH) in patients with hepatitis B virus (HBV)-related cirrhosis. Materials and Methods: A cohort of 166 consecutive adult pati Read More

Objective: The purpose of the study was to determine DTI properties of brain metastases in subjects with Non-Small Cell Lung Carcinoma (NSCLC) to evaluate whether there was a correlation between DTI findings and Programmed Cell Death Ligand-1 (PD-L1). Methods: The study population (n:22) was assigned to PD-L1 negative (Group 1: PD-L1 expression<% 50) (n=11) or positive (Group 2: PD-L1 expression ≥%50) (n=11). Read More

Background: In recent years, Deep Learning (DL) algorithms have emerged endlessly and achieved impressive performance, which makes it possible to accelerate Magnetic Resonance (MR) image reconstruction with DL instead of Compressed Sensing (CS) methods. However, a DL-based MR image reconstruction method has always suffered from its heavy learning parameters and poor generalization ability so far. Therefo Read More

Background: This study was conducted to measure the entrance skin dose in radiographic examinations of pediatric patients in King Khalid Hospital, Majmaah, Saudi Arabia. Introduction: Children have been given special attention since they are often regarded as especially vulnerable to potential hazards. The pediatric population is more susceptible to radiation than the adult population for certain tumor types. Objective: The aim Read More
