Added-Value of Diffusion-Weighted Imaging (DWI) and Dynamic Contrast-Enhanced (DCE-MRI) Magnetic Resonance Imaging in the Preoperative Assessment of Cervical Cancer.

Purpose: To evaluate the added-value of diffusion-weighted imaging (DWI) and dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) in the preoperative assessment of carcinoma cervix.

Methods: This prospective study was carried out on histopathologically proven 45 patients of carcinoma cervix presented to a tertiary care hospital with bleeding per vagina between August 2017 and July 2018. Relevant local per vaginal examination and MRI examination of the pelvis were performed.

Role of MRI in Differentiating Various Posterior Cranial Fossa Space-Occupying Lesions Using Sensitivity and Specificity: A Prospective Study.

Background: Any abnormal space-occupying posterior fossa lesion may directly involve the vital structures like the brain stem, cranial nerves, cerebellum, vertebrobasilar artery, and venous sinuses, which makes the surgical approach and total excision very difficult. Hence for these reasons, precise evaluation of posterior fossa lesion with MRI is a must to visualize the vital structures, which helps in planning and safe surgery.  Objective: This study aimed to evaluate the added value of diffusion-weighted imaging and magnetic resonance spectroscopy in the localization, extension, characterization, differentiation of various posterior fossa space-occupying lesions, and correlating with the histopathological result.

MRI Spectrum of Japanese Encephalitis in Northeast India: A Cross-Sectional Study.

 Japanese encephalitis (JE) is an arthropod-borne flavivirus infection having high mortality and morbidity. This study was performed to evaluate the conventional magnetic resonance imaging (MRI) findings in JE and to find out any difference between pediatric and adult JE.  This retrospective study was performed on serologically positive 54 JE patients presented to a tertiary care hospital with acute encephalitic symptoms between April 2016 and October 2019.

Added Value of Diffusion-Weighted Magnetic Resonance Imaging in Differentiating Musculoskeletal Tumors Using Sensitivity and Specificity: A Retrospective Study and Review of Literature.

Background: Diffusion-weighted imaging (DWI) provides added value to conventional MRI imaging in diagnosing and differentiating various benign and malignant musculoskeletal tumors.

Objective: The study aims to evaluate the diagnostic efficacies of diffusion-weighted imaging along with the conventional MRI sequences for differentiating benign and malignant musculoskeletal tumors using sensitivity and specificity.

Materials And Methods: This retrospective study was carried out on 73 histopathologically proven patients of various musculoskeletal tumors who presented to a tertiary care center between March 2017 to October 2018.

Magnetic resonance imaging evaluation of posterior spinal tuberculosis: a cross-sectional study.

Background: Isolated posterior spinal (element) tuberculosis (TB) is uncommon compared to classical anterior spinal or para-discal TB. Here, we report magnetic resonance imaging (MRI) findings of posterior spinal TB in 19 patients without involvement of the vertebral body and intervertebral disc.

Purpose: To evaluate the MRI findings in isolated posterior spinal (element) TB.

Castleman's disease associated with calcifying fibrous tumor: A rare association with review of literature.

Castleman's disease is a rare disease characterized by unicentric or multicentric enlargement of the lymph node, and it is mostly of the hyaline vascular type. Calcifying fibrous tumor is a neoplasm characterized by large areas of hyalinized collagen with paucicellular areas along with dystrophic calcification and scattered lymphoplasmacytic infiltrates. There are only five case reports to describe an association between these two entities.

Spectrum of MRI Appearance of Mayer-Rokitansky-Kuster-Hauser (MRKH) Syndrome in Primary Amenorrhea Patients.

Introduction: Mayer-Rokitansky-Kuster-Hauser (MRKH) synd-rome is a malformation in female genital tract due to interrupted embryonic development of para-mesonephric ducts leading to uterine and proximal vagina aplasia or hypoplasia.

Aim: To analyse the MRI findings in females suspected of MRKH syndrome in a primary amenorrhea workup.

Materials And Methods: A cross-sectional study comprising of 11 patients of MRKH syndrome presented in a tertiary care centre from March 2016 to February 2017 evaluated in 1.

Characterisation of musculoskeletal tumours by multivoxel proton MR spectroscopy.

Objective: The purpose of this study is to evaluate the role of multi-voxel proton MR spectroscopy in differentiating benign and malignant musculoskeletal tumours in a more objective way and to correlate the MRS data parameters with histopathology.

Methods And Materials: A hospital-based prospective study was carried out comprising 42 patients who underwent MRI examinations from 1 July 2013 to 30 June 2014. After routine sequences, single-slice multi-voxel proton MR spectroscopy was included at TE-135 using the PRESS sequence.

Natural Killer Cell Lymphoma: A Case with Classification Dilemma.

Non-Hodgkins lymphoma of the Natural Killer (NK) cell type is rare. World Health Organisation recognises 3 NK-cell phenotypic entities; extranodal NK/T cell lymphoma, nasal type (ENK/TL); aggressive NK cell leukaemia (ANKL); and chronic lymphoproliferative disorders of NK cells (CLPD-NK) which is classified as a provisional entity. Though specific clinical, morphological and immunophenotypic criteria have been laid down to diagnose these conditions there may however, be considerable variations in the clinical presentation making diagnosis difficult.
