Radiomics analysis for distinctive identification of COVID-19 pulmonary nodules from other benign and malignant counterparts.

This observational study investigated the potential of radiomics as a non-invasive adjunct to CT in distinguishing COVID-19 lung nodules from other benign and malignant lung nodules. Lesion segmentation, feature extraction, and machine learning algorithms, including decision tree, support vector machine, random forest, feed-forward neural network, and discriminant analysis, were employed in the radiomics workflow. Key features such as Idmn, skewness, and long-run low grey level emphasis were identified as crucial in differentiation.

Radiomics as a non-invasive adjunct to Chest CT in distinguishing benign and malignant lung nodules.

In an observational study conducted from 2016 to 2021, we assessed the utility of radiomics in differentiating between benign and malignant lung nodules detected on computed tomography (CT) scans. Patients in whom a final diagnosis regarding the lung nodules was available according to histopathology and/or 2017 Fleischner Society guidelines were included. The radiomics workflow included lesion segmentation, region of interest (ROI) definition, pre-processing, and feature extraction.

Case report: Metastatic myxoid liposarcoma arising from the right atrium extends as cardiac tamponade-A rare case of atrial oncology.

The reported incidence of liposarcomas in ~2,000 cases annually results in about 30% of myxoid liposarcomas. Cardiac myoxid liposarcomas are very rare; their presentation could be cardiac tamponade, due to direct compression of the tumor and/or pericardial effusion. In this report, we describe a patient who presented with pericardial effusion secondary to myoxid liposarcomas from the right atrium, an extremely rare presentation of liposarcomas in the heart.

Successful Outcome of Metastatic Pancreatoblastoma in an Adolescent: A Case Report and Review of the Literature.

Pancreatoblastoma, an orphan disease, is the most common malignant epithelial neoplasm of the pancreas in children. With vague clinical features, diagnosis is made by radiological suggestions and histopathology. The presence of metastatic disease and inoperable/incomplete excision remains the poor prognostic markers.

Radiomic Analysis of Positron-Emission Tomography and Computed Tomography Images to Differentiate between Multiple Myeloma and Skeletal Metastases.

Context: Multiple myeloma and extensive lytic skeletal metastases may appear similar on positron-emission tomography and computed tomography (PET-CT) in the absence of an obvious primary site or occult malignancy. Radiomic analysis extracts a large number of quantitative features from medical images with the potential to uncover disease characteristics below the human visual threshold.

Aim: This study aimed to evaluate the diagnostic capability of PET and CT radiomic features to differentiate skeletal metastases from multiple myeloma.

Unusual sites of Rosai-Dorfman disease in children: 5 years experience from tertiary care paediatric haemato-oncology centre.

Rosai-Dorfman disease (RDD) is a rare histiocytic disorder, usually presenting with massive lymphadenopathy. The involvement of extra nodal sites, bone and nodal sites like mediastinum are rare. Clinical data of three cases of extra nodal RDD who were admitted in our paediatric haemato-oncology unit were analysed in the last 5 years.

Telangiectatic Osteosarcoma in a Young Child - A Case Report and Review of the Literature.

Introduction: Osteosarcoma (OS) is one of the most common primary malignant bone tumors in children and adolescents. OS incidence varies significantly with age and peak incidence is in adolescent age group. Telangiectatic osteosarcoma (TOS) is an unusual variant of OS, forming 3-10% of all OSs.

Correlation between Reference Tissue Normalized 18F-Fluorodeoxyglucose Positron Emission Tomography/Computed Tomography Standardized Uptake Value Max of Nodal and Extranodal Sites in Lymphomas: An Empirical Study.

Context: Extranodal (EN) lymphomas involve sites other than lymph nodes (LNs), spleen, thymus, and the pharyngeal lymphatic ring. The highest standardized uptake value (SUV) max of the LN can aid in the diagnosis of EN site lymphomatous infiltrations over inflammation or infection especially when there are no contrast-enhanced computed tomography (CT) changes.

Aims: The purpose of this study was to find the significance of correlation between absolute SUVmax and mediastinal blood pool (mbSUVmax) and liver (lvSUVmax) normalized SUVmax of EN sites and the most fluorodeoxyglucose (FDG) avid LN in patients with primary and secondary EN involvement in Non-Hodgkin's and Hodgkin's Lymphoma.

Prognostic significance of metabolic tumour volume and maximum standard uptake value of fluor-18-fluorodeoxyglucose positron emission tomography with computed tomography in nasopharyngeal carcinoma.

Aim Of The Study: To evaluate the prognostic role of markers of fluor-18-fluorodeoxyglucose positron emission tomography with computed tomography (F-FDG-PET-CT), such as maximum standard uptake value (SUV) and metabolic tumour volume (MTV) measured at primary and nodal disease, and their clinical significance in terms of predicting treatment outcomes and survival.

Material And Methods: Between January 2017 and January 2020, 20 case records of nasopharyngeal carcinoma patients who underwent F-FDG-PET-CT as part of staging workup before radiotherapy and as a part of response evaluation after radiotherapy were retrospectively reviewed.

Results: At a median follow-up of 34.

Temporomandibular joint changes in oral submucous fibrosis- A magnetic resonance imaging study.

Background: The aim of this study was to assess the Temporomandibular joint changes as a consequence of varying degrees of restricted mouth opening in Oral Submucous Fibrosis patients.

Material And Methods: The study Population was divided into 2 groups namely Group C- 40 TMJ's of 20 age and gender matched healthy controls and Group P- 40 TMJ's of 20 OSMF patients who were further subdivided into Group II,III,IV based on their restriction in mouth opening. MRI of bilateral TMJ was obtained in closed mouth position.
