Purpose Few options are available for pain relief in patients with bone metastases who fail standard treatments. We sought to determine the benefit of radiofrequency ablation (RFA) providing refractory secondary involving bone. Patients and Methods Thirty-one US 12 European painful osteolytic were treated image-guided RFA using a multitip needle. Treated had ≥ 4/10 either failed or poor candidates treatments such as radiation opioid analgesics. Using Brief Pain Inventory–Short Form, worst...
Nonanastomotic biliary strictures that involve only the tree of graft occur after orthotopic liver transplantation in patients with hepatic artery thrombosis, chronic ductopenic rejection and ABO blood group incompatibility. This complication may also absence these known risk factors. The major focus our study was to evaluate factors for nonanastomotic stricturing unknown cause transplantation. Results demonstrate development is strongly associated duration cold ischemic storage allografts...
PURPOSE: To determine the safety and efficacy of radio-frequency (RF) ablation for pain reduction, quality life improvement, analgesics use reduction in patients with skeletal metastases. MATERIALS AND METHODS: Over 10 months, 12 adult a single painful osteolytic metastasis whom radiation therapy or chemotherapy had failed who reported severe (pain score ≥ 4 [scale 0–10]) over 24-hour period were treated percutaneous imaging-guided RF multitined electrode while under general anesthesia....
Purpose: To prospectively determine the safety and effectiveness of percutaneous cryoablation for reduction pain, improvement in activities daily life, use analgesic medications patients with painful metastatic lesions involving bone. Materials Methods: This study was compliant HIPAA approved by institutional review board. Written informed consent obtained. During 18 months, 14 (eight men, six women; age range, 21–72 years; mean age, 54 years) one or two bone, a score 4 greater out 10 worst...
To determine the sensitivity and specificity of helical computed tomography (CT) for diagnosis acute pulmonary embolism.This prospective study included 47 patients who underwent arteriography evaluation possible embolism. Tailored CT were performed within 24 hours each other. Each scan was interpreted by two chest radiologists, blinded to arteriographic results, at institutions. interpretations compared with findings on bilateral selective arteriograms vascular radiologists one...
The clinical significance and outcome of nonanastomotic strictures dilatations involving only the biliary tree graft with a radiological appearance ischemia is unknown. Therefore we analyzed grafts 128 patients to evaluate biochemical, histological features that prompted diagnosis ischemic-type stricture this complication. Ischemic-type were diagnosed in 25 (19%). Initial function was similar all patients, whether or not complication developed. Most occurred between 1 4 mo after orthotopic...
PURPOSE: To determine the sensitivity and specificity of contrast material-enhanced electron-beam computed tomography (CT) in diagnosis pulmonary embolism (PE). MATERIALS AND METHODS: Sixty patients suspected having PE were prospectively evaluated with angiography contrast-enhanced CT. Thirty-eight underwent ventilation-perfusion (V-P [also known as V/Q]) scanning. The vasculature was divided into 12 anatomic zones. CT angiographic findings correlated on a patient-by-patient basis for each...
To assess whether a nonparticulate steroid (dexamethasone, 10 mg) is less clinically effective than the particulate steroids (triamcinolone, 80 mg; betamethasone, 12 in lumbar transforaminal epidural injections (TFESIs) subjects with radicular pain or without radiculopathy.Retrospective observational study noninferiority analysis of dexamethasone relative to steroids.Single academic radiology management practice.Three thousand six hundred forty-five TFESIs at L4-5, L5-S1, S1 neural foramina,...
Contrast material-enhanced electron-beam computed tomography (CT) (100-msec scan time) was performed to image the pulmonary vasculature in 86 patients, each suspected of having a embolism (PE). Thromboembolic material demonstrated 39 patients; no emboli were 47. In 25 angiographic or pathologic proof available. There 19 proved positive CT scans, four negative one false-negative scan, and false-positive scan. 21 patients with correlation, evidence thromboembolic disease seen 88 vascular...
Nonanastomotic hilar bile duct strictures developed in 16 of 152 patients who underwent liver transplantation. The type pretransplantation disease did not significantly affect the likelihood stricture formation. Possible causes biliary include hepatic artery occlusion, ductopenic arteriopathic rejection, and cytomegalovirus infection; however, five had without these complications. Hilar within 3 months after transplantation 11 patients. Strictures began as a slight common irregularity...
Background. Transforaminal epidural steroid injections (TFESI) have demonstrated efficacy and effectiveness in treatment of radicular pain. Despite little evidence efficacy/effectiveness, interlaminar (ILESI) are advocated by some as primary therapy for pain due to purported greater safety.

To assess the clinical effectiveness of single lumbar transforaminal epidural steroid injections (TFESIs) in subjects with radicular pain or without radiculopathy. Retrospective observational series. Single academic radiology management practice. Two thousand twenty-four undergoing TFESIs at L4-5, L5-S1, S1 neural foramina. Subjects were assessed a numerical rating scale (NRS, 0–10) and Roland–Morris disability questionnaire (R–M, 23-point Deyo modification) prior to TFESI 2 weeks months...
Setting. Interventional procedures directed toward sources of pain in the axial and appendicular musculoskeletal system are performed with increasing frequency. Despite presence evidence-based guidelines for such procedures, there wide variations practice. Case reports serious complications as spinal cord infarction or infection from spine injections lack appropriate context create a misleading view risks appropriately interventional procedures. Objective. To evaluate adverse event rate at...
Background Intra-articular corticosteroid (IACS) injection and peri-articular are commonly used to treat musculoskeletal conditions. Results vary by region, but most studies report short-term benefit with mixed results on long-term relief. Publications showed adverse events from single injections. Recommended effective doses were lower than those currently clinicians. Methods Development of the practice guideline for joint injections was approved Board Directors American Society Regional...
Study Design. A case of internal carotid artery impingement by the tip a well-positioned C1–C2 transarticular screw is presented along with pilot study involving radiologic and anatomic evaluation human cadaveric specimens. Objective. To raise awareness that may be in close proximity to anterior aspect atlas at risk injury during placement screws or C1 lateral mass screws. Summary Background Data. our knowledge, no cases have been reported fixation atlas. Methods. presented. The rotation...
