Background: Helicobacter pylori (HP) affect nearly 50% of the world's population and can colonize the submucosal and mucosal layers of the stomach wall, causing inflammation leading to a thickening of these layers. The study aimed to evaluate the application value of transabdominal ultrasonography combined with elastography in the prediction of HP using HP Fecal Antigen Test as gold standard.

Method: This prospective case-control study was conducted in 174 participants classified into three groups: Group A: Symptomatic patients with thickened stomach antral and evident HP infection on fecal antigen test results, Group B: Symptomatic patients with thickened antral and no evident HP infection on fecal antigen test results, and Group C: control group of asymptomatic individuals with negative HP screening to predict the diagnostic accuracy of B-mode ultrasound and elastography in the prediction of HP pylori.

Introduction: Radiography is a crucial healthcare specialty that requires ongoing research to advance imaging technologies and techniques. Despite this, radiographers are faced with obstacles such as time constraints, lack of resources, and the need for training on new technologies, which can discourage their research involvement. This study aims to provide a more representative understanding of the radiography research culture in Saudi Arabia, building upon previous studies.

BACKGROUND Muscle hernias are an uncommon condition typically found in the extremities; masseter muscle hernia is even rarer. However, it is important for clinicians and radiologists to be aware of this possibility. Intramuscular venous malformation (IMVM) is also uncommon and mostly found in the head, neck, and extremities.

Article Synopsis
  • Twin reversed arterial perfusion (TRAP) sequence is a rare complication in identical twin pregnancies sharing a placenta, characterized by one normal "pump" fetus and one abnormal, typically nonviable, "acardiac" fetus.
  • The acardiac fetus relies on the pump fetus for blood supply, which can lead to heart failure and anomalies in the pump fetus, resulting in high mortality rates.
  • Early detection using ultrasound techniques is crucial for managing TRAP, as interrupting the blood flow to the acardiac twin can help reduce the strain on the pump fetus and improve its chances of survival.

Objectives: To establish local DRL (LDRL) for computed tomography (CT) examinations based on size-specific dose estimates (SSDEs), which consider patient size. The concept of diagnostic reference level (DRL) was introduced to limit patient exposure to unnecessary radiation. However, traditional DRL values do not consider patient size.

Background: There is a paucity of information about the clinical features and angiographic findings in young patients with acute myocardial infarction (MI), especially in the Arab Peninsula countries.

Objective: The aim of this study was to assess the proposed risk factors, clinical presentation, and angiographic findings of acute myocardial infarction in young adults.

Methods: This prospective study included young (range, 18 to 45 years) patients who presented with acute MI based on clinical evaluation, laboratory investigation, and electrocardiogram, and they underwent a coronary angiography procedure.

Article Synopsis
  • Breast cancer (BC) is a widespread health issue among women, and early diagnosis is crucial for effective management.
  • A study analyzed the ultrasound (US) features in 326 female patients diagnosed with BC to evaluate their effectiveness in distinguishing between benign and malignant tumors using statistical methods.
  • The results showed that certain US features, like irregular shape and non-circumscribed margins, were strongly associated with malignancy, highlighting that while US is a sensitive tool for detecting BC, its specificity is lower due to similarities between benign and malignant characteristics.

Coronavirus disease 2019 (COVID-19) is an epidemic viral disease caused by a novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Despite the excessive number of neurological articles that have investigated the effect of COVID-19 on the brain from the neurological point of view, very few studies have investigated the impact of COVID-19 on the cerebral microstructure and function of the brain. The aim of this study was to summarize the results of the existing studies on cerebral microstructural changes in COVID-19 patients, specifically the use of quantitative volumetric analysis, blood oxygen level dependent (BOLD), and diffusion tensor imaging (DTI).

Hydatid cyst is a common name for the larval stage of a tapeworm species of , which is transmitted from animals to humans via the fecal-oral route. Hydatid cysts predominantly affect the liver (75%), followed by the lung (15%), and they can affect many organs in the human body. Medical imaging modalities are the keystone for the diagnosis of hydatid cysts with high sensitivity and specificity.

Tuberculosis (TB) is a bacterial infection with ; it is a public health problem worldwide and one of the leading causes of mortality. Since December 2019, the COVID-19 pandemic has created unprecedented health challenges and disrupted the TB health services, especially in high-burden countries with ever-increasing prevalence. Extrapulmonary and even pulmonary TB are an important cause of nonspecific clinical and radiological manifestations and can masquerade as any benign or malignant medical case, thus causing disastrous conditions and diagnostic dilemmas.

Article Synopsis
  • - Tuberous sclerosis complex (TSC) is a genetic syndrome linked to mutations in the TSC1 or TSC2 genes, leading to abnormal growths in various organs and a wide range of symptoms that can vary in severity.
  • - The article discusses two cases of TSC, both beginning with seizures in infancy, highlighting diagnostic tools such as CT and MRI, with the first case diagnosed through brain lesions and the second through a prenatal heart tumor.
  • - Literature revealed that neurological symptoms, especially seizures, were key in identifying TSC, followed by abdominal and prenatal imaging findings, while other symptoms like skin and renal issues were less common in leading to diagnosis.

Hydatid cyst (cystic echinococcosis) is a chronic parasitic infection by the larval stage of the cestode that is called resulting in the development of cystic lesions in animals and humans. In this report, we describe a rare phenotype of hydatid cyst in the breast of a 23-year-old female presented with breast mass in the left upper outer quadrant for 3 months with palpable left axillary lymph nodes. Both US and mammography provided a picture of complex suspicious cystosolid lesion with amorphous micro-calcification (BIRAD-4A).

Aim: The association between hearing acuity and white-matter (WM) microstructure integrity was evaluated in a normal healthy population with a variety of hearing acuity using an automated tractography technique known as TRACULA (TRActs Constrained by UnderLying Anatomy) in order to investigate whether hearing acuity decline is correlated with brain structural connectivity.

Methods: Forty healthy controls were recruited to this study, which used a Siemens 3T Trio with a standard eight-channel head coil. Hearing acuity was assessed using pure-tone air conduction audiometry (Amplivox 2160, with Audiocups to eliminate noise and allow accurate pure-tone audiometry).
