Accuracy of MRI skeletal age estimation for subjects 12-19. Potential use for subjects of unknown age.

Introduction: In forensic practice, there is a growing need for accurate methods of age estimation, especially in the cases of young individuals of unknown age. Age can be estimated through somatic features that are universally considered associated with chronological age. Unfortunately, these features do not always coincide with the real chronological age: for these reasons that age determination is often very difficult.

Value of MRI of the hand and the wrist in evaluation of bone age: preliminary results.

Purpose: To evaluate bone age determination using MRI of the hand and wrist.

Materials And Methods: A total of 179 (78 female and 101 males, 11 to 16 years old) subjects of 252 normal volunteers met entrance criteria. A low field open magnet (0.

MR enterography: relationship between intestinal fold pattern and the clinical presentation of adult celiac disease.

Purpose: To correlate the clinical presentation of adult celiac disease with various intestinal fold patterns using MR-enterography.

Materials And Methods: Fifty-four consecutive adult celiac patients (34 female, 20 male, 18 to 62 years) were studied by MR-enterography. Two radiologists blinded to the patients' clinical history evaluated in consensus MR studies, classifying the intestinal fold pattern into four categories: (a) no fold abnormalities, (b) isolated loss of folds in the duodenum, (c) jejunization of ileum, and (d) jejuno-ileal fold pattern reversal.

MR arthrography of the glenohumeral joint: modified posterior approach without imaging guidance.

Institutional review board approval and informed consent were obtained. The purpose of the study was to prospectively perform magnetic resonance (MR) arthrography of the glenohumeral joint by using modified posterior approach without ultrasonographic or fluoroscopic guidance. A solution containing 0.

Adult celiac disease: MRI findings.

The purpose of our report is to describe a spectrum of findings of celiac disease at MR enterography. MR enterography is a non-invasive, feasible, and reproducible imaging technique for the evaluation of small bowel. Findings on MR enterography, similar to those of conventional barium studies, may suggest a diagnosis of celiac disease.

Adult celiac disease: what is the role of MRI?

Purpose: To evaluate the ability of MRI to identify intra- and extraintestinal findings of celiac disease in an adult population.

Materials And Methods: Forty-one subjects (18 men and 23 women; mean age = 41.3 years; 31 with biopsy-proven celiac disease, and 10 healthy volunteers) underwent MRI of the small bowel.

Initial experience with magnetic resonance fluoroscopy in the evaluation of oesophageal motility disorders. Comparison with manometry and barium fluoroscopy.

The aim of this paper was to assess the diagnostic value of magnetic resonance (MR) fluoroscopy in the study of oesophageal motility disorders and to compare MR fluoroscopy results with those of manometry and barium contrast radiography. Twenty-five subjects referred for dysphagia and three patients in follow-up after pneumatic dilatation of the lower oesophageal sphincter to treat severe achalasia underwent esophageal manometry, barium contrast radiography and MR fluoroscopy. Examinations were performed on a 1.

Small intestine contrast ultrasonography: an alternative to radiology in the assessment of small bowel disease.

Background: Radiology and transabdominal ultrasonography (TUS) are used in the evaluation of the small bowel; however, the former technique is limited by radiation exposure, and the latter by its inability to visualize the entire small bowel.

Aim: To evaluate the diagnostic accuracy of small intestine contrast ultrasonography (SICUS) to assess the presence, number, site, and extension of small bowel lesions.

Subjects And Methods: TUS, SICUS, and small bowel follow-through (SBFT) were performed in 148 consecutive patients (78 women; age range, 12 to 89 yr), 91 with undiagnosed conditions, and 57 with previously diagnosed Crohn's disease (CD).

MR of the small bowel with a biphasic oral contrast agent (polyethylene glycol): technical aspects and findings in patients affected by Crohn's disease.

Purpose: To report our experience using MR of the small bowel with polyethylene glycol (PEG) solution as an oral contrast agent in a population of adults and children with known Crohn's disease.

Materials And Methods: 40 patients (29 males; 11 females), 15 adults (age range 24-52 years) and 25 children (age range 5-17 years), with known Crohn's disease, underwent MR of the small bowel using a supeconductive 1.5 T magnet, and polyethylene glycol solution as an oral contrast agent.

MR imaging of the small bowel using polyethylene glycol solution as an oral contrast agent in adults and children with celiac disease: preliminary observations.

Objective: The purpose of our report is to describe morphologic abnormalities of the small bowel in a population of patients with known celiac disease using MR imaging with polyethylene glycol solution as an oral contrast agent.

Conclusion: Polyethylene glycol-enhanced MR imaging is a noninvasive (no ionizing radiation is used), feasible, and reproducible imaging technique in both adult and pediatric populations. Findings on polyethylene glycol-enhanced MR imaging, similar to those of conventional barium studies, may suggest a diagnosis of celiac disease because the technique can not only reveal intestinal involvement but also show extraintestinal findings.

GI distension in severe ulcerative colitis.

Objectives: In previous retrospective studies in patients with severe ulcerative colitis (UC), small bowel distension was found to characterize a subgroup of patients at higher risk for both toxic megacolon (TMC) and multiple organ dysfunction syndrome (MODS). In this study we prospectively evaluated the prevalence of GI distension and its relationship to clinical outcome in patients with severe UC.

Methods: Of 109 consecutive inpatients with acute UC (admitted to the GI Unit of the University of Rome during the period 1995-2000), 45 had severe colitis.
