Mean Intracranial Volume of Brain among Patients with Normal Magnetic Resonance Imaging Referred to the Department of Radiology and Imaging of a Tertiary Care Centre.

Introduction: The measurement of brain volume is an important aspect of the assessment of brain structure and function. However, limited data is available on brain volumetry in the Nepalese population. The study aimed to find the mean intracranial volume of the brain among patients with normal magnetic resonance imaging referred to the Department of Radiology and Imaging of a tertiary care centre.

Correlation of Imaging Findings with Molecular Subtypes of Breast Cancer.

Background: Ultrasound and Mammography are first-line imaging in breast cancer. The management of malignant breast lesions depends on molecular biomarkers in the tumor cells. This study aims to correlate different imaging findings in breast carcinoma with immune-histology subtypes.

Magnetic Resonance Imaging Evaluation of Suspected High-Altitude Cerebral Edema in Patients from High Altitude.

Background: Trekkers in high altitude of Himalayas could lead to Acute Mountain Sickness and High Altitude Cerebral Edema. This study was conducted to evaluate magnetic resonance imaging findings among the clinically suspected High Altitude Cerebral Edema patients rescued from high altitudes in Nepal Himalayas.

Methods: 49 patients with clinically suspected High Altitude Cerebral Edema were retrospectively evaluated in this cross-sectional study who were sent for a brain magnetic resonance imaging.

Zinner Syndrome: A Case Report of Rare Urogenital Anomaly.

Zinner Syndrome is a rare urogenital tract anomaly with unilateral renal agenesis, ipsilateral seminal vesicle cyst, and ipsilateral ejaculatory duct obstruction. The syndrome occurs due to an insult to the development of the paramesonephric duct during embryogenesis. Patients may present late due to dysejaculation as a result of obstruction of the ejaculatory duct or commonly remain asymptomatic.

Normal Anatomy and Variants of Renal Vasculature with Multidetector Computed Tomography in a Tertiary Care Hospital: A Descriptive Cross-sectional Study.

Introduction: Preoperative multisection computed tomography evaluation can provide necessary anatomic information in minimally invasive surgeries. This study was done to estimate the preva-lence and pattern of variations of renal vasculature through contrast-enhanced computed tomogra-phy in patients referred to the radiology department of a tertiary care hospital.

Methods: A descriptive cross-sectional study was conducted from 6th April 2016 to 6th April 2017.

Anatomical Variations in Circle of Willis in Patients Undergoing CT Cerebral Angiography in a Tertiary Hospital in Nepal: A Descriptive Cross-sectional Study.

Introduction: Variation in Circle of Willis is a commonly encountered entity in patients undergoing computed tomography angiography, identification of which is crucial in the management of patients with vascular pathologies. The aim of the study was to find out the anatomical variations in the Circle of Willis in patients undergoing Computed Tomography cerebral angiography in a tertiary hospital in Nepal.

Methods: This is a descriptive cross-sectional study involving 95 patients using convenient sampling techniques who were sent to the Department of Radiology and Imaging, Tribhuvan University Teaching hospital, for further evaluation of suspected vascular pathologies in the brain from April 2017 to September 2017.

Current Imaging Trends in COVID-19 Pneumonia.

COVID-19 has rapidly emerged as a pandemic threatening lives and healthcare systems worldwide. With the emergence of the disease in Nepal, all faculties of medicine need to be well prepared to face the challenge. Fortunately, now plenty of research is available to facilitate our preparedness in the war against COVID-19.

Role of MR Morphology and Diffusion-Weighted Imaging in the Evaluation of Meningiomas: Radio-Pathologic Correlation.

Introduction: Preoperative differentiation of benign, atypical and malignant meningiomas would significantly help in surgical planning and treatment. The aim of this study is to look at radio-morphologic behavior of various histopathological types and grades of meningiomas and their diffusion characteristics.

Methods: We performed an analytical cross-sectional study including all patients operated on for meningiomas at our hospital during January 2016 to July 2018.

Renal Cortical Elastography: Normal Values and Variations.

Introduction: Renal cortical elastography has shown conflicting but promising results in evaluation of chronic kidney disease and other renal disorders. The purpose of this study was to establish a normogram of renal cortical elasticity values and assess their variation between right and left kidney and their relation with age, gender, body mass index, renal dimensions and skin to cortex distance.

Methods: The study was a hospital based cross sectional study performed at Tribhuvan University Teaching Hospital, a tertiary care center in Kathmandu, Nepal.

Transcranial doppler ultrasonography cerebral blood flow dynamics study of neurosurgical patients in peri-agonal period with fixed dilated or non-reacting pupils.

Introduction: Fixed dilated and unreactive pupils are a harbinger of imminent death in neurosurgical patients, signifying that the brainstem is not functioning. Transcranial Doppler (TCD) ultrasonography is a noninvasive, bedside method of determining the flow velocities in the basal cerebral arteries, used extensively in various neurosurgical conditions.

Aims And Objectives: To study the cerebral blood flow dynamics of neurosurgical patients in peri-agonal period with fixed dilated or non reacting pupils using TCD.

Pancreatic pseudocyst or mucinous cystadenocarcinoma of pancreas? A diagnostic dilemma.

Pancreatic cystic neoplasm is difficult to distinguish from pseudocyst as clinical and radiological evidences may not be sufficient to make an accurate diagnosis. This may result in misdiagnosis with inappropriate management. Hence, every effort should be made for their distinction to avoid internal drainage procedures for neoplasms instead of extirpation.

A rare case of synchronous colocolic intussusception in association with Peutz-Jeghers syndrome.

Adult intussusception is rare and is almost always associated with a lead point. Polyposis syndromes are a common cause of adult intussusceptions, with polyps acting as lead points. Peutz-Jeghers syndrome is associated with benign hamartomatous polyps and mucocutaneous pigmentation.

Predictors of duration and treatment failure of severe pneumonia in hospitalized young Nepalese children.

Background: Pneumonia in young children is still the most frequent cause of death in developing countries. We aimed to identify predictors for recovery and treatment failure in children hospitalized with severe pneumonia.

Methods: We enrolled 610 Nepalese children, aged 2 - 35 months from February 2006 to June 2008.
