In clinical routine, lower limb analysis relies on conventional X-ray (2D view) or computerised tomography (CT) Scan (lying position). However, these methods do not allow 3D analysis in standing position. The aim of this study is to propose a fast and accurate 3D-reconstruction-method based on parametric models and statistical inferences from biplanar(More)
PURPOSE To describe the normal anatomy of the finger flexor tendon pulley system, with anatomic correlation, and to define criteria to diagnose pulley abnormalities with different imaging modalities. MATERIALS AND METHODS Three groups of cadaveric fingers underwent computed tomography (CT), magnetic resonance (MR) imaging, and ultrasonography (US). The(More)
OBJECTIVE To evaluate percutaneous computed tomography (CT)-guided intracystic and intra-articular steroid injections for the treatment of lumbar facet joint cyst causing radicular pain. METHODS A single-centre prospective study involving 120 consecutive patients with symptomatic lumbar facet joint cyst-induced radicular pain was done (72 women, 48 men).(More)
PURPOSE To evaluate in vivo magnetic resonance (MR) imaging with a conventional 1.5-T system for depiction and tracking of intravascularly injected superparamagnetic iron oxide (SPIO)-labeled mesenchymal stem cells (MSCs). MATERIALS AND METHODS This study was conducted in accordance with French law governing animal research and met guidelines for animal(More)
OBJECTIVE To determine the tolerability, effectiveness and outcomes of percutaneous image-guided cryoablation on inoperable extra-abdominal desmoid tumors. METHODS Between 2011 and 2012, 13 patients (mean age 39.3 years, range 15-74) with inoperable extra-abdominal desmoid tumors were consecutively treated with cryoablation (17 tumors treated in 17(More)
Pseudocysts, lipomas, infarcts and simple cysts of the calcaneus are described as different entities in the medical literature. However, some evolutions or associations may suggest a relationship which is not yet demonstrated in all cases. The aim of this article is to describe each lesion and emphasize their different characteristics that may suggest a(More)
Relevance of posture assessment has been reported in case of spine disorders. This study explores the interest in quantifying posture using 3D reconstruction from biplanar X-rays in free standing position and a force plate. 93 patients consulting for spine disorders were divided ('3D deformity', 'sagittal imbalance' and 'mild deformity') and compared with(More)
The purpose of this study was to evaluate the detection and characterization of macrophage infiltration in native and transplanted kidneys using ultrasmall superparamagnetic iron oxide particles (USPIO). Among 21 patients initially enrolled, 12 scheduled for renal biopsy for acute or rapidly progressive renal failure (n = 7) or renal graft rejection (n = 5)(More)
Ankle impingement is a common condition occurring secondary to sprain or repeated microtrauma. Clinical symptoms are chronic pain located in the affected region and limited range of ankle motion. There are three types of ankle impingement syndrome: anterior impingement, which can be subdivided into anterolateral, anteromedial and purely anterior(More)
OBJECTIVE This article describes the appearance of the anterolateral recess of the posttraumatic ankle on CT arthrography and clearly shows the benefit of this technique in the diagnosis of soft-tissue impingement. MATERIALS AND METHODS The study was carried out on 44 patients examined by CT arthrography and arthroscopy for chronic, posttraumatic ankle(More)
