Standard-protocol moving-table magnetic resonance angiography for planning of interventional procedures in patients with peripheral vascular occlusive disease.

Purpose: This study aimed to evaluate the usefulness of magnetic resonance angiography (MRA) for the planning of interventional procedures in the lower extremity vascular territory.

Materials And Methods: Patients with peripheral vascular occlusive disease (PVOD) underwent MRA for planning of percutaneous interventional treatment. Digital subtraction angiography was performed in patients scheduled for interventional treatment and served as the standard of reference.

Magnetic resonance imaging of the lumbar spine after epidural and nerve root injection therapy: evaluation of soft tissue changes.

Objective: Magnetic resonance imaging (MRI) was performed to evaluate soft tissue changes after nerve root and epidural injections in lumbar spine in patients with radiculopathy.

Materials/methods: Patients underwent a multiple-shot injection protocol to nerve root/epidural space. The MRI protocol included T1-weighted, T2-weighted, STIR, and contrast-enhanced, fat-saturated T1-weighted sequences before and after treatment.

Clinical and serological characteristics of progressive facial hemiatrophy: a case series of 12 patients.

Background: Progressive facial hemiatrophy (PFH) is characterized by a slowly progressive atrophy of soft tissues and in some cases bony structures. Coexisting features of localized scleroderma (LS) are commonly observed, indicating the close nature of both disorders.

Objective: We sought to investigate clinical, serological, and radiographic findings in PFH from 278 patients with LS and to discuss the relationship to linear scleroderma en coup de sabre (LSCS).

Effective dose of CT- and fluoroscopy-guided perineural/epidural injections of the lumbar spine: a comparative study.

The objective of this study was to compare the effective radiation dose of perineural and epidural injections of the lumbar spine under computed tomography (CT) or fluoroscopic guidance with respect to dose-reduced protocols. We assessed the radiation dose with an Alderson Rando phantom at the lumbar segment L4/5 using 29 thermoluminescence dosimeters. Based on our clinical experience, 4-10 CT scans and 1-min fluoroscopy are appropriate.

Imaging of infected total arthroplasty with Tc-99m-labeled antigranulocyte antibody Fab'fragments.

Objective: The objective of this study was to evaluate the diagnostic accuracy of Tc-99m-labeled antigranulocyte antibody Fab' fragments in infected total arthroplasty.

Materials And Methods: A total of 38 immunoscintigrams were evaluated retrospectively with 15 to 25 mCi Tc-99m-labeled antigranulocyte antibody-Fab' fragments. The final diagnosis was assessed by articular puncture or intraoperative sampling.

Imaging osteomyelitis with Tc-99m-labeled antigranulocyte antibody Fab' fragments.

PURPOSE The purpose of this study was to evaluate the diagnostic value of Tc-99m-labeled antigranulocyte antibody fragments in the diagnosis of osteomyelitis. MATERIALS AND METHODS Thirty immunoscintigrams were evaluated retrospectively with 740 MBq (20 mCi) Tc-99m-labeled antigranulocyte antibodies. The final diagnoses were confirmed by histology, magnetic resonance imaging, computed tomography, and clinical follow-up.
