Abstract BACKGROUND: This study sought to describe the results of a single‐arm multicenter clinical trial using image‐guided percutaneous cryoablation for palliation painful metastatic tumors involving bone. METHODS: Over 44‐month period, 61 adult patients with 1 or 2 bone metastases score 4 more on scale 0 10 (≥4/10) worst pain in 24‐hour period who had failed refused conventional treatment were treated cryoablation. Patient and quality life was measured Brief Pain Inventory prior...
To determine whether a three-dimensional isotropic resolution fast spin-echo sequence (FSE-Cube) has similar diagnostic performance as routine magnetic resonance (MR) imaging protocol for evaluating the cartilage, ligaments, menisci, and osseous structures of knee joint in symptomatic patients at 3.0 T.This prospective, HIPAA-compliant, institutional review board-approved study was performed with waiver informed consent. FSE-Cube added to 3.0-T MR 100 (54 male median age 32 years 46 female...
To retrospectively compare the diagnostic performance of 1.5- and 3.0-T magnetic resonance (MR) imaging protocols for evaluating articular cartilage knee joint in symptomatic patients.This HIPAA-compliant study was performed with a waiver informed consent from institutional review board. The group consisted 200 patients undergoing MR examination at 1.5 T (61 men, 39 women; mean age, 38.9 years) or 3.0 (52 48 39.1 years), who also underwent subsequent arthroscopic surgery. All examinations...
Background: Systems for classifying cervical spine injury most commonly use mechanistic or morphologic terms and do not quantify the degree of stability. Along with neurologic function, stability is a major determinant treatment prognosis. The goal our study was to investigate reliability method quantifying subaxial (C3-C7) injuries. Methods: A quantitative system developed in which an analog score 0 5 points assigned, on basis fracture displacement severity ligamentous injury, each four...
To compare the diagnostic performance of iterative decomposition water and fat with echo asymmetry least-squares estimation (IDEAL)-spoiled gradient-recalled (SPGR) that standard magnetic resonance (MR) arthrography sequences for detecting grading cartilage lesions within hip joint during MR arthrography.Following institutional review board approval, 67 consecutive arthrograms were retrospectively reviewed independently by three musculoskeletal radiologists one fellow. IDEAL-SPGR images...
Abstract Purpose: To compare six new three‐dimensional (3D) magnetic resonance (MR) methods for evaluating knee cartilage at 3.0T. Materials and Methods: We compared: fast‐spin‐echo cube (FSE‐Cube), vastly undersampled isotropic projection reconstruction balanced steady‐state free precession (VIPR‐bSSFP), iterative decomposition of water fat with echo asymmetry least‐squares estimation combined spoiled gradient (IDEAL‐SPGR) (IDEAL‐GRASS), multiecho in acquisition (MENSA), coherent...
Increased youth participation in sports has resulted increased injury tolls due to shifts toward competitive at earlier ages, training intensity and competition schedules, as well specialization into one sport. The physiology of the growing musculoskeletal system makes athlete particularly vulnerable specific types injuries. Radiologists must understand differences between pediatric adult athletes recognize particular injuries which these young are prone. Imaging pertinent clinical details...
Patients with symptomatic Hoffa fat pad impingement often exhibit edema on MRI. We studied two patient groups to determine the association between MRI and clinical symptoms of impingement.We 34 consecutive patients an diagnosis no injury in prior year (group 1) 47 a knee examination 2). Two sports medicine physicians reviewed records confirm or exclude impingement. musculoskeletal radiologists independently scored 12 locations for presence edema, noting epicenter.Seventeen group 1 had...
The experimental procedure described is designed to allow calculation of the radiation sterilization dose for medical devices any desired standard sterility assurance. makes use results a series tests on device samples exposed doses from 0.2 1.8 Mrad in increments. From test data 10(-2) level determined. A formula that allows value called DS be calculated. This an estimate effective resistance heterogeneous microbial population remaining tail portion inactivation curve at and above. used as...
US is commonly performed to help diagnose traumatic peripheral nerve injury and entrapment neuropathy, particularly with superficial nerves, where higher spatial resolution provides an advantage over MRI. Other advantages of include dynamic evaluation, easy contralateral comparison, fewer implant contraindications, less artifact from ferromagnetic debris, facile needle guidance for perineural injections. The authors review emphasis on grading neuropathy describe best-practice techniques...
Several previous studies reported that the signal contacting meniscal surface in a recurrent tear on MR arthrography had intensity equal to of intraarticular contrast material. Because we failed diagnose tears using this criterion, reviewed our knee arthrograms patients who prior surgery.On arthrograms, may be or less than adjacent gadolinium
