Article Synopsis
  • Cardiac MRI is the best method for detecting and assessing heart muscle conditions, with late gadolinium enhancement helping in patient classification and management.
  • Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is a rare congenital heart defect that can show myocardial enhancement on MRI.
  • This report discusses unusual mid myocardial late gadolinium enhancement found in three adult patients with ALCAPA, differing from typical enhancement patterns.

Purpose: To compare diagnostic accuracy in localization and detection of extraprostatic extension (EPE), seminal vesicle invasion (SVI), lymph node involvement (LNI) between PSMA PET MRI and multiparametric MRI (mpMRI) in carcinoma prostate.

Methods: We did a prospective study of consecutive men with biopsy-proven prostate cancer who underwent radical prostatectomy between July'2020 and Dec'2021 at our institution. Patients underwent PSMA PET MRI imaging.

Article Synopsis
  • Patients with hypertrophic cardiomyopathy (HCM) face a risk of sudden death, especially if they have major risk markers, leading to the consideration of implantable cardioverter-defibrillators and cardiac magnetic resonance (CMR) imaging for risk assessment.
  • A study aimed to develop deep-learning models based on electrocardiogram (ECG) data to identify high-risk imaging features in HCM patients, using a cohort from Tufts Medical Center in Boston.
  • The ECG deep-learning models showed reliable identification of high-risk features and could potentially reduce the need for CMR testing by using a screening strategy that combines echocardiography with selective CMR recommendations.

Objective: Positron emission tomography (PET) imaging has assumed an essential role in the presurgical evaluation of epileptogenic foci in drug-resistant epilepsy by identifying the hypometabolic cerebral cortex. The authors herein designed a pilot study to test a novel technique of PET asymmetry after anatomical symmetrization coregistered to MRI (PASCOM), utilizing interhemispheric metabolic asymmetry on interictal fluorine 18-labeled fluorodeoxyglucose (FDG)-PET to better localize the epileptogenic zone.

Methods: The authors analyzed interictal FDG-PET scans from 23 patients with drug-resistant epilepsy, mean (± SD) age 20.

Purpose: To analyze statistically derived threshold values of volumetric MRI and 18F fluorodeoxyglucose (FDG) PET asymmetry, independent of normative data, for non-invasive detection/exclusion of temporal lobe epilepsy (TLE).

Methods: We retrospectively analyzed amygdalohippocampal volumetry and temporal FDG PET metabolism in 33 patients (age: 29.27 ± 8.

Introduction: Whole-body bone scintigraphy (WBBS) is considered to be the standard of care in the initial skeletal evaluation of patients with carcinoma prostate. Magnetic resonance imaging (MRI) is a potential alternative technique for detecting bone metastasis. The objective of this study was to compare the diagnostic performance of WBBS with a single-photon emission computed tomography-computed tomography (SPECT-CT) correlation of the suspicious WBBS lesions to the axial skeleton (AS)-MRI in diagnosing bone metastasis in patients with carcinoma prostate.

Multiple Sclerosis (MS) is an autoimmune-neurodegenerative disorder managed therapeutically by modulating lymphocytes activity which has potential in disease management. Prohibitin 1(PHB) that controls the reactive oxygen species (ROS) and present on the activated lymphocytes have significance in the therapy of MS as esters of fumaric acid that regulates ROS is in phase II/III clinical trials. Thus, we evaluated the expression levels of PHB1 in experimental autoimmune encephalomyelitis (EAE), the animal model of MS and on MS patient's lymphocytes.

Aim: To retrospectively analyze the percutaneous transhepatic techniques and their outcome in the management of biliary strictures in living donor liver transplant (LDLT) recipients.

Materials And Methods: We retrieved the hospital records of 400 LDLT recipients between 2007 and 2015 and identified 45 patients with biliary strictures. Among them, 17 patients (37.

Objectives: We present a case series of patients who underwent perirolandic resection for medically refractory focal epilepsy due to focal cortical dysplasia (FCD). Our aim was to specifically evaluate the outcome of a surgical strategy intended for seizure freedom while preserving primary motor cortex function.

Materials And Methods: Thirteen patients undergoing perirolandic resection for pharmacoresistant focal epilepsy between 2010 and 2015 who demonstrated histological evidence of FCD were selected from a prospectively maintained database.

Objectives: We present the imaging findings of a newly identified lethal arteriopathy associated with a novel mutation in the gene encoding fibulin-4, occurring in a distinct community from southern India.

Material And Methods: A total of 31 children from a distinct population subgroup who presented with characteristic arterial dilatation and tortuosity were studied. All children except one belonged to unrelated families from an ethno-religious group (Muslim) from the northern coastal belt of southern India.

In this study, we have reported the incorporation of a multi-modal contrast agent based on hydroxyapatite nanocrystals, within a poly(caprolactone)(PCL) nanofibrous scaffold by electrospinning. The multifunctional hydroxyapatite nanoparticles (MF-nHAp) showed simultaneous contrast enhancement for three major molecular imaging techniques. In this article, the magnetic resonance (MR) contrast enhancement ability of the MF-nHAp was exploited for the purpose of potentially monitoring as well as for influencing tissue regeneration.

Objective: The purposes of this article are to describe the technical factors in performing 64-MDCT of pulmonary atresia with ventricular septal defect (PA-VSD), to describe the anatomic variations in pulmonary arterial circulation and other associated anomalies, and to describe the postoperative evaluation of this condition.

Conclusion: The management of this complex condition has been largely determined by the morphology of pulmonary arteries and the extracardiac sources of pulmonary blood supply. Although echocardiography and catheter angiography are the traditional imaging techniques used to diagnose PA-VSD, 64-MDCT has become a valuable noninvasive imaging technique in comprehensive evaluation of this condition.
