We study the reproducibility of quantitative imaging features that are used to describe tumor shape, size, and texture from computed tomography (CT) scans non-small cell lung cancer (NSCLC). CT images dependent on various scanning factors. focus characterizing image reproducible in presence variations due patient factors segmentation methods. Thirty-two NSCLC nonenhanced were obtained Reference Image Database Evaluate Response data set. The tumors segmented using both manual (radiologist...
Tumor cell survival relies upon adaptation to the acidic conditions of tumor microenvironment. To investigate potential acidosis mechanisms, we examined effect low pH (6.7) on human breast carcinoma cells. Acute exposure reduced proliferation rate, induced a G1 cycle arrest, and increased cytoplasmic vacuolization. Gene expression analysis revealed elevated levels ATG5 BNIP3 in acid-conditioned cells, suggesting cells exposed may utilize autophagy as mechanism. In support this hypothesis,...
Nonsmall cell lung cancer is a prevalent disease. It diagnosed and treated with the help of computed tomography (CT) scans. In this paper, we apply radiomics to select 3-D features from CT images toward providing prognostic information. Focusing on cases adenocarcinoma nonsmall tumor subtype larger data set, show that classifiers can be built predict survival time. This first known result make such predictions scans cancer. We compare feature selection approaches. The best accuracy when...
Purpose Measurement variance affects the clinical effectiveness of PET-based measurement as a semiquantitative imaging biomarker for cancer response in individual patients and planning trials. In this study, we measured test-retest reproducibility SUV measurements under practice conditions recorded recognized deviations from protocol compliance. Methods Instrument performance calibration, display, analyses conformed to manufacture recommendations. Baseline 18F-FDG PET/CT examinations were...
Abstract Determination of the apparent diffusion coefficient (ADC) prostate in men ( n = 60) with raised prostate‐specific antigen (PSA) or an abnormal digital rectal examination (DRE) prior to transrectal ultrasound (TRUS) guided biopsy using endorectal DWI is reported. Patients were categorized into different groups based on their PSA levels. The mean ADC was calculated from a number regions interest (ROIs) for whole peripheral zone (PZ) and central gland (CG). A total 1108 ROIs analyzed...
Pulmonary arterial hypertension as a result of the occlusion branches pulmonary vasculature is characterized by rise in mean pressure above 20 mmHg. endarterectomy preferred treatment modality for chronic thromboembolic hypertension. Anesthetic challenges include management right ventricular (RV) dysfunction, low baseline oxygen saturation, pre-operative deranged coagulation profile due to anticoagulant use, specific requirements deep hypothermic circulatory arrest, and need cerebral...
Although the metastatic involvement of heart is more common, incidence Primary Cardiac Tumour very less (0.001- 0.03 percent population). Myxomas, commonest Tumours, are usually benign. However, they can manifest symptoms systemic involvement, depending upon their location. 75% myxomas located in left atria heart, although no chamber immune. Commonly have pedunculated morphology, with peduncle attached to atrial inter-atrial septum. The common when atria. Diagnosing these be challenging,...
A CT-scan is a vital tool for the diagnosis of lung cancer via tumor detection. Developing classifier to make use information in images could provide non-invasive alternative histopathological techniques such as needle biopsy identify types. Image features extracted from 74 objects are used classifying Classification done into two major classes non-small cell tumors, Adenocarcinoma and Squamous-cell Carcinoma, each constituting 30% all tumors. In this first its kind investigation, large...
Abstract Results of the evaluation transrectal ultrasound (TRUS) guided needle biopsy voxels identified as suspicious malignancy on magnetic resonance spectroscopic imaging (MRSI) in a large cohort men ( n = 83) with abnormal digital rectal examination (DRE) [prostate specific antigen (PSA) 0–4 ng/ml] or PSA less than 10 ng/ml, are reported. Three‐dimensional 1 H MRSI was carried out at 1.5 T using pelvic‐phased array coil combination an endorectal surface coil. Voxels were classified based...
