Diagnostic Accuracy of MRI in Internal Derangement of Knee in Comparison to Arthroscopy MRI Vs Arthroscopy in Knee Injury

Background: The knee joint (KJ) is one of the largest as well as most complicated joints in the human body. The knee is one of the most frequently injured joints, either as a separated injury or as a common portion in patients with multiple traumas. MRI has completely transformed the field of radio diagnosis because it provides superior soft tissue (ST) contrast. Also, it has appeared to be highly useful in muscle, brain, abdominal, and soft tissue imaging. The MRI is non-invasive which provides significantly better ST contrast, and requires less imaging time while having fewer artefacts. Aims & Objectives: To compare the accuracy of diagnostic [True Positive (TP), True Negative (TN), False Positive (FP), as well as False Negative (FN)] of MRI & arthroscopy in diagnosing internal derangement (ID) of the knee. To determine the function of MRI in selecting patients for arthroscopy. Material and Methods: This research is a cross-sectional investigation wherein patients who were thought to have an internal knee dislocation (IKD) were given an MRI and some were chosen for an arthroscopy. Most MRIs were done on a 1.5 tesla MRI scanner. The results of the MRI were written down.&nbsp

Hemodynamic Evaluation of Coarctation of Aorta Using Phase: Contrast Magnetic Resonance Imaging and Its Comparison with Echocardiographic Findings Evaluation of Coarctation of Aorta

Background: Coarctation of aorta (CoA) occurs when a small section of the aorta narrows in the luminal. CoA is one of the most popular congenital CL (cardiac lesions), and it is responsible for five to ten percent of all instances of congenital HD (heart disease). CoA can result in a variety of complications. Aims & Objectives: This research was undertaken to determine the occurrence of related CL and valvular disorders in patients with CoA. Materials and Methods: This research was carried out in the Department of Radiodiagnosis and Imaging (DORAI), Sher-i-Kashmir Institute of Medical Sciences (SKIMS) Tertiary Care Hospital, Srinagar, JK, India over a period of 2 years on patients referred from the Department of Cardiology. The patients who had been detected with CoA were given a PC-MRI to check their blood flow, and the comparison was made to the Echocardiographic study results. Results: Spin-echo (S-E) images of the level of the aortic arch (AA) as well as aortic isthmus (AI) showed narrowing in nineteen situations, according to the researchers. In eleven of the twenty situations, there was a significant amount of collateral circulation (CC). CC was significant in six out of eleven situations of serious stenosis

Role of 3.0 T MRI in the Evaluation of Mesial Temporal Sclerosis Using Loss of Hippocampal Striations as Diagnostic Parameter

Background: Mesial Temporal Sclerosis, also known as MTS, is a condition that causes medial temporal lobe epilepsy (MTLE) and is characterized by the loss of hippocampal neurons. Multiple researches on individuals with hippocampal sclerosis (HS) have demonstrated that MRI (magnetic resonance imaging) is an exhaustive method for locating the EF (epileptogenic focus). Aims & Objectives: To study Partial Loss of Hippocampal Striations (PLHS) as a diagnostic parameter using 3.0 Tesla MRI to increase the confidence of diagnosing Mesial Temporal Sclerosis (MTS). Material & methods: This prospective research was performed in 55 patients who had undergone 3T (GE SIGNA HDX) brain imaging under epilepsy protocol that included T2 axial, coronal FLAIR and 3D SPGR hippocampal volume assessment in addition to high resolution T2 coronal imaging over a period of two years at Department of Radiodiagnoses and Imaging (DORAI), Bharat Scans, Chennai, India

New vegetation type map of India prepared using satellite remote sensing: comparison with global vegetation maps and utilities

A seamless vegetation type map of India (scale 1: 50,000) prepared using medium-resolution IRS LISS-III images is presented. The map was created using an on-screen visual interpretation technique and has an accuracy of 90%, as assessed using 15,565 ground control points. India has hitherto been using potential vegetation/forest type map prepared by Champion and Seth in 1968. We characterized and mapped further the vegetation type distribution in the country in terms of occurrence and distribution, area occupancy, percentage of protected area (PA) covered by each vegetation type, range of elevation, mean annual temperature and precipitation over the past 100 years. A remote sensing-amenable hierarchical classification scheme that accommodates natural and semi-natural systems was conceptualized, and the natural vegetation was classified into forests, scrub/shrub lands and grasslands on the basis of extent of vegetation cover. We discuss the distribution and potential utility of the vegetation type map in a broad range of ecological, climatic and conservation applications from global, national and local perspectives. Weused 15,565 ground control points to assess the accuracy of products available globally (i.e., GlobCover, Holdridge’s life zone map and potential natural vegetation (PNV) maps). Hence we recommend that the map prepared herein be used widely. This vegetation type map is the most comprehensive one developed for India so far. It was prepared using 23.5m seasonal satellite remote sensing data, field samples and information relating to the biogeography, climate and soil. The digital map is now available through a web portal (http://bis.iirs.gov.in)
