Plantar fascia evaluation with a low-field MRI scanner in weight-bering position: our initial experience in patients with plantar fasciitis and in healthy volunteers

Purpose: To assess the usefulness of weight-bearing examination of the ankle performed with a low-field MRI scanner in the evaluation of plantar fascia in normal healthy volunteers and in patients with a clinical evidence of plantar fasciitis. Methods and Materials: We retrospectively evaluated ankle MR examinations in two groups of 40 patients each, performed between January and July 2008. Spin echo T1W, Gradient echo T2W, and Short Tau Inversion Recovery (STIR) images were acquired with a 0.2 T scanner (G-Scan, Esaote Biomedica, Genoa, Italy) in both weight-bearing position and normal conventional supine position. A dedicated extremities transmitter/receiver coil was used. The lesion site…

ARRYTHMOGENIC RIGHT VENTRICULAR CARDIOMYOPATHY: MULTISLICE COMPUTED TOMOGRAPHY FEATURES

Classificazione ed imaging delle sindromi conflittuali della caviglia

Obiettivi didattici: Rivedere la classificazione ed illustrare i vari aspetti delle sindromi conflittuali alla radiografia convenzionale (RC), alla tomografia computerizzata multistrato (TCms), all'ecografia (US), alla risonanza magnetica (RM) ed all'artro-RM. Introduzione: Le sindromi conflittuali della caviglia dipendono da molte cause che possono essere distinte dal tipo di tessuto che determina il conflitto (osseo, fibroso, sinoviale).In generale, la classificazione delle sindromi conflittuali della caviglia prende in considerazione la sede anatomica relativa all'articolazione tibio-tarsica, e pertanto esse possono essere classificate in anteriore, antero-mediale, antero-laterale, poste…

La pubalgia nello sportivo: quadri RM di “Osteite Pubica"

La pubalgia è una sindrome dolorosa, a volte a carattere invalidante, che colpisce sia gli sportivi agonisti che quelli amatoriali, rappresenta il 2-5% delle patologie correlate all’attività sportiva agonistica e non sempre le sue cause sono facilmente diagnosticabili. L’osteite pubica rappresenta una delle principali cause di dolore inguinale e colpisce gli sportivi nel 0,5-0,7% dei casi. Dal settembre 2003 all’agosto 2004, 40 atleti, 37 uomini e 3 donne (età compresa tra 18 e 37 anni; età media: 24 anni), con diagnosi clinica di pubalgia sono stati sottoposti a RM del bacino. In tutti i casi la sintomatologia era caratterizzata da dolore mono (33%) o bilaterale (67%) con irradiazione alla…

Role of high-resolution ultrasonography without and with real-time spatial compound imaging in evaluating the injured posterior cruciate ligament: preliminary study.

This study sought to compare high-resolution ultrasonography (HRUS) without and with compound imaging in evaluating the injured posterior cruciate ligament (PCL). Thirteen patients with a magnetic resonance imaging (MRI) diagnosis of PCL lesions (ten acute and three chronic) and 20 healthy controls underwent conventional and compound HRUS performed by the same radiologist who was blinded to the subjects' case-control status. The PCL was scanned in a longitudinal direction in all cases. HRUS images were assessed for PCL thickness by two other radiologists blinded to the number and type of PCL injury. PCLs were classified as normal or injured, and the latter as having acute or chronic injurie…

Role of high-resolution ultrasound in guiding treatment of idiopathic plantar fasciitis with minimally invasive techiniques

The aim of this study was to assess the reliability of peri-fascial oedema as a sonographic criterion for selecting the most appropriate treatment (ultrasound-guided corticosteroid injection or ultrasound-guided extracorporeal shock wave therapy) of idiopathic plantar fasciitis (IPF).Sixty-four patients with a clinical diagnosis of unilateral refractory IPF, treated conservatively for at least 8 weeks, were studied with high-resolution ultrasound (HRUS). Pain intensity was evaluated with a visual analogue scale (VAS). HRUS was used to confirm IPF and identify the presence of peri-fascial oedema. Patients with an HRUS diagnosis of IPF were grouped according to the presence (A) or absence (B)…

STUDY OF CAPILLARY ABSORPTION KINETICS BY X-RAY CT IMAGING TECHNIQUES: A SURVEY ON SEDIMENTARY ROCKS OF SICILY

Sedimentary rocks are natural porous materials with a great percent of microscopic interconnected pores: they contain fluids, permitting their movement on macroscopic scale. Generally, these rocks present porosity higher then metamorphic rocks. Under certain points of view, this feature represents an advantage; on the other hand, this can constitute an obstacle for cultural heritage applications, because the porosity grade can lead to a deterioration of the lapideous monument for water capillary absorption. In this paper, CT (Computerized Tomography) image techniques are applied to capillary absorption kinetics in sedimentary rocks utilized for the Greek temples as well as baroc monuments, …

Multislice multiecho T2* cardiovascular magnetic resonance for detection of the heterogeneous distribution of myocardial iron overload.

Purpose To assess the tissue iron concentration of the left ventricle (LV) using a multislice, multiecho T2* MR technique and a segmental analysis. Materials and Methods T2* multiecho MRI was performed in 53 thalassemia major patients. Three short-axis views of the LV were obtained and analyzed with custom-written software. The myocardium was automatically segmented into 12 segments. The T2* value on each segment as well as the global T2* value were calculated. Cine dynamic images were also obtained to evaluate biventricular function parameters by quantitative analysis. Results For the T2* global value, the coefficient of variation (CoV) for intra-/interobserver and interstudy reproducibili…

Necrotizing fasciitis of the face: A life-threatening condition

Necrotizing fasciitis (NF) is a highly aggressive infectious process, polymicrobial in nature, involving soft tissues with a high risk of rapid spread through superficial and deep fascial planes and muscular layers. Cervical NF is quite rare, is mostly of odontogenic origin, and may be complicated by descendant mediastinitis with a very high mortality rate. Systemic conditions impairing the patient's immune competence, such as diabetes, may play a predisposing role. An effective treatment strategy includes prompt diagnosis (clinical findings, local microbiological tests, blood culture and, if deemed necessary, histopathology), broad-spectrum antibiotic therapy as early as possible which sho…

Water capillary absorption in porous media in different wettability conditions studied by Quantitative MRI and X-ray CT

X-ray computed tomography (CT) and magnetic resonance imaging (MRI) have been successfully applied to study both the capillary properties of several samples of Lecce stone and the performances of treatments used for protection and conservation of historical stone artifacts. The presence of water inside the sample may be visualized by both MRI and X-ray CT. For the treated samples, the different dynamics of water absorption gives indirectly the efficacy of the polymer in the rock.

HIGH-RESOLUTION ULTRASONOGRAPHY (HRUS) OF THE MENISCAL CYST OF THE KNEE : OUR EXPERIENCE

Purpose. This study was undertaken to assess the diagnostic accuracy of high-resolution ultrasonography (HRUS) in the detection of meniscal cysts. Materials and methods. Over a 2-year period, 1,857 patients underwent magnetic resonance imaging (MRI) of the knee for traumatic or degenerative disorders. All patients with MRI evidence of a meniscal cyst were studied by HRUS. HRUS was also performed on an equal number of patients without MRI evidence of meniscal cyst who were used as a control group. All HRUS examinations were conducted by a radiologist blinded to the MRI findings. Sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of HRUS were assesse…
