Prognostic Significance of Magnetic Resonance Imaging in Detecting Diffuse Axonal Injuries: Analysis of Outcomes and Review of Literature.

Background: Diffuse axonal injury (DAI) is the brain injury characterized by extensive lesions in the white matter tracts over a widespread area. DAI is one of the most common and devastating types of traumatic brain injury and a major cause of unconsciousness and persistent vegetative state after head trauma. It occurs in about half of all cases with severe head trauma.

Role of Bedside Transcranial Ultrasonography in the Assessment of Cerebral Hemodynamics in Decompressive Craniectomy Patients with Cranioplasty: A Single Centre Experience.

Background: Intracerebral hemorrhage is a leading cause of death and disability worldwide. After intracerebral hemorrhage, cerebral blood flow (CBF) becomes extremely low approaching ischemic thresholds. Concurrently, CBF velocities become strongly correlated to CBF itself post-injury.

Sonological Appearance of Epidermoid Cyst of the Spleen: A Rarity.

Epidermoid cyst of the spleen is a rare, benign cystic lesion of congenital origin. Although most epidermoid cysts of the spleen are asymptomatic and detected incidentally on ultrasonography, the entity needs to be included in the differential diagnosis of cystic lesion mimics of the spleen, especially in patients with left hypochondriac pain. This case report describes the typical sonological appearance of epidermoid cyst of the spleen in a 31-year-old male.

Ectopic Cervical Thymus in an Adult: A Rare Presentation.

Ectopic cervical thymus is an essentially benign condition related to embryological development of the thymus and is exceedingly rare among the adult population. Precise and early diagnosis of the entity on high-resolution ultrasonography may help avoid further investigations and unnecessary surgical intervention. This case report describes the typical sonological appearance of ectopic cervical thymus in a 44-year-old male.

First Carpometacarpal Joint Anatomy and Osteoarthritis: MR Imaging Overview.

The first carpometacarpal (CMC) joint consists of seven ligaments. The magnetic resonance imaging (MRI) examination of the first CMC joint should be performed in a high field 1.5/3 T MRI with a dedicated hand coil for high-resolution images.

Appendix around Ileocolic Intussusception with Acute Appendicitis: A Rare Presentation.

Intussusception and appendicitis share similar clinical features. However, their concurrent occurrence is exceedingly rare. Appendix involvement in intussusception must be ruled out when appendix is not visualized on high-resolution ultrasonography in cases with ileocolic intussusception.

High-Resolution Ultrasonography of Renal Oncocytoma Presenting with Symptomatic Hematuria and Urinary Bladder Clot Retention-A Rare Occurrence.

Renal oncocytomas are asymptomatic, benign tumors often encountered incidentally on various imaging modalities. Renal oncocytomas comprise 5-7% of primary renal neoplasms and are derived from cells of the distal renal tubule. We present a case report of renal oncocytoma in a 22-year-old male having right-sided flank pain and symptomatic gross hematuria with a giant urinary bladder clot retention.

High-Resolution Ultrasonography in the Assessment of Lumbar Radiculoplexus Neuropathy in Diabetics: Preliminary Results of a Case-Control Study.

 The traditional diagnosis of lumbar radiculoplexus neuropathy (LRN) is based on a classical sequence of symptoms and targeted electrodiagnostic examination by means of electromyography. Ultrasonography reliably indicates the level of lumbar radiculopathy by assessing edema mesial to the site of compression.  This case-control study was undertaken at a tertiary care hospital between July 2017 and June 2019 on 15 diabetic patients with symptoms of LRN.

Diagnostic Accuracy and Prognostic Significance of Point-Of-Care Ultrasound (POCUS) for Traumatic Cervical Spine in Emergency care setting: A Comparison of clinical outcomes between POCUS and Computed Tomography on a Cohort of 284 Cases and Review of Literature.

Background: The cervical spine is injured in approximately 3% of major trauma patients, and 10% of patients with serious head injury. Therefore, clearance of the cervical spine in multitrauma patients is a critically important task. This is particularly important, considering that there is a positive correlation between a Glasgow Coma Scale of <14 and cervical spine injury.

Review of lung ultrasound findings in coronavirus disease 2019 (COVID-19): Effectiveness, applications and approach to lung ultrasound during times of a pandemic.

As of 22 April 2020, there are 6 countries with >100,000 cases, 21 countries with 1000 to 10,000 confirmed cases and 53 countries with between 1000 and 10,000 confirmed cases of COVID-19. Six articles (5 research articles and 1 review article) with a total of 159 cases delineating the equipment, protocol, techniques, indications and follow-up management of COVID-19 were identified in a PUBMED search evaluating the role of lung Ultrasound. In the current review article, 55%-60% of the patients with COVID-19 were male; the median age has been reported between 34 and 59 years.

Embryological considerations and evaluation of congenital anomalies of craniovertebral junction: A single-center experience.

Objectives: Craniovertebral junction (CVJ) abnormalities constitute a group of treatable neurological disorders, especially in the Indian subcontinent. Thus, it is essential that clinicians should be able to make a precise diagnosis of abnormalities and rule out important mimickers on multidetector computed tomography (MDCT) as this information ultimately helps determine the management, prognosis, and quality of life of patients. CVJ is the most complex part of the cervical region.

Isolated Intramuscular Cysticercosis of the Biceps Diagnosed on High-Resolution Ultrasonography.

High-resolution ultrasound clinches the diagnosis of intramuscular cysticercosis which is a rare finding. Here, we present a case of isolated intramuscular cysticercosis diagnosed on high-resolution ultrasonography in a 46-year-old gentleman who presented with a linear swelling in the flexor aspect of the left arm in the long head of the biceps.

F-fluorodeoxyglucose positron emission tomography/computed tomography imaging review of benign lesions of the thorax.

2-deoxy-2-(Fluorine-18) fluoro-D-glucose (F-FDG) positron emission tomography/computed tomography (PET/CT) has been used exclusively to diagnose malignancies. However, increased F-FDG uptake is not always limited to malignant lesions. This imaging review demonstrates the physiological F-FDG uptake of normal structures in the thorax and illustrates many benign pathological lesions with standardized uptake value >2.

Diagnostic accuracy and false-positive rate of chest CT as compared to RT-PCR in coronavirus disease 2019 (COVID-19) pneumonia: A prospective cohort of 612 cases from India and review of literature.

Background: At present, the diagnosis of COVID-19 depends on real-time reverse transcriptase polymerase chain reaction (RT-PCT). On imaging, computed tomography (CT) manifestations resemble those seen in viral pneumonias, with multifocal ground-glass opacities and consolidation in a peripheral distribution being the most common findings. Although these findings lack specificity for COVID-19 diagnosis on imaging grounds, CT could be used to provide objective assessment about the extension of the lung opacities, which could be used as an imaging surrogate for disease burden.

Diagnostic accuracy of chest computed tomography in improving the false negative rate as compared to reverse transcriptase polymerase chain reaction in coronavirus disease 2019 pneumonia: A cross sectional analysis of 348 cases from India.

Background: Early differentiation between emergency department (ED) patients with and without coronavirus disease 2019 (COVID-19) is very important. The diagnosis of COVID-19 depends on real-time reverse transcriptase polymerase chain reaction (RT-PCR). On imaging, computed tomography (CT) manifestations resemble those seen in viral pneumonias, with multifocal ground-glass opacities and consolidation in a peripheral distribution being the most common findings.

Semi-quantitative analysis of F fluorodeoxyglucose uptake in the assessment of disease activity and therapeutic response in rheumatoid arthritis: An institutional experience.

F fluorodeoxyglucose (F-FDG) positron emission tomography (PET) can be used to image synovial inflammation in patients with rheumatoid arthritis (RA). Recently, clinical application of novel therapies for RA, such as tumor necrosis factor-α (TNF-α) inhibitor and anti-interleukin-6 receptor antibody, has been introduced. The radiological assessment of disease activity changes of patients who underwent these therapies will help the clinicians to obtain more information about the patients and to decide drug withdrawal or change of medication.

Role of F-FDG positron emission tomography in carotid atherosclerotic plaque imaging: A systematic review.

Stroke and other thromboembolic events in the brain are often due to carotid artery atherosclerosis, and atherosclerotic plaques with inflammation are considered particularly vulnerable, with an increased risk of becoming symptomatic. Positron emission tomography (PET) with 2-deoxy-2-[Fluorine-18] fluoro-D-glucose (F-FDG) provides valuable metabolic information regarding arteriosclerotic lesions and may be applied for the detection of vulnerable plaque. At present, however, patients are selected for carotid surgical intervention on the basis of the degree of stenosis alone, and not the vulnerability or inflammation of the lesion.

Imaging appearances of giant cell tumor of the bone.

Giant cell tumor (GCT) of bone is a benign, locally aggressive lytic lesion in the subarticular location occurring in skeletally mature individuals. Acute hemarthrosis from pathological fracture of GCT should be considered in the differential diagnosis for acute swelling of the knee. Here we describe the imaging appearances of GCT on conventional radiography and magnetic resonance imaging (MRI).
