There has been recent interest in the application of machine learning techniques to neuroimaging-based diagnosis. These methods promise fully automated, standard PC-based clinical decisions, unbiased by variable radiological expertise. We recently used support vector machines (SVMs) separate sporadic Alzheimer's disease from normal ageing and fronto-temporal lobar degeneration (FTLD). In this study, we compare results those obtained radiologists. A binary diagnostic classification was made...
To compare dynamic gadolinium-enhanced T1-weighted magnetic resonance (MR) imaging with nonenhanced and T2-weighted MR thin-section computed tomography (CT) for the demonstration of osteoid osteomas.The images 11 patients pathologically proven osteomas who underwent imaging, CT were retrospectively reviewed. Images obtained all three techniques scored conspicuity osteoma relative to surrounding bone. Time-enhancement curves generated from signal intensity measurements these lesions adjacent...
To determine the prevalence of hip and pelvic fractures in emergency department (ED) patients with pain negative standard initial radiographs.This was a retrospective, cohort study at an academic, community-based ED. ED presenting during one-year period for whom plain-film radiograph obtained were included. Eligible identified by query electronic records. Plain radiographs magnetic resonance images (MRIs) ordered discretion treating physician. Initial plain read point care board-certified...
We have observed that osteoid osteomas are frequently surrounded by thin curvilinear or serpiginous low-density grooves in the surrounding bone on CT examinations. believe these represent prominent enlarged feeding arterioles, corresponding to recently published histologic findings. This study was performed assess sensitivity and specificity of this vascular groove sign for differentiating from other radiolucent lesions.The group consisted 42 patients with pathologically proven osteomas. The...
PURPOSE: To determine whether breast augmentation implants interfere with detection of cancer and to characterize the projections that offer an improvement in disease. MATERIALS AND METHODS: The mammographic examinations, clinical presentation, pathologic findings were retrospectively reviewed 18 patients who underwent silicone gel-filled implants. RESULTS: At diagnosis, 16 (89%) had palpable abnormalities. Standard views negative 17 (94%). Modified implant compression (used displacement)...
The purpose of our study was to correlate clinically determined joint stability with the degree bone fusion in ankle or subtalar on MDCT examinations after arthrodesis.We performed a retrospective review 42 consecutive from 29 patients. All patients had previously undergone arthrodesis their joints and persistent recurrent hindfoot pain. Two musculoskeletal radiologists examined consensus sagittal 2-mm-thick reformatted slices, measuring each image length surface fused portion space. sum...
BRAF V600E mutation has been reported to show a high specificity for papillary thyroid carcinoma (PTC). Using this marker upgrade 'indeterminate' or 'suspicious' fine needle aspiration (FNA) cytology 'malignant' could potentially allow one-stage therapeutic total thyroidectomy.For 14-month period, FNA specimens in the Thy3-5 categories, which are UK equivalents of indeterminate (Thy3a, atypical; Thy3f, follicular), suspicious malignancy (Thy4) and malignant (Thy5) Bethesda System, underwent...
