Introductory Comments: Direct MR arthrography (MRR) consists of MR imaging of a joint after injecting dilute gadolinium or straight saline into the joint. Over the last decade, this technique has become widely accepted for imaging numerous intraarticular disorders. Prior to that, CT arthrography (CTR) had been gaining steam as an improvement in imaging some joints over standard contrast arthrog...

Triple-compartment wrist arthrography is currently considered the optimal technique for evaluating carpal instability, because injection of contrast agent into the radiocarpal joint alone can fail to reveal ligamentous disruption due to a ball-valve tear. Unfortunately, triple-compartment arthrography can be time consuming for both the patient and the radiologist. This report describes a techni...

OBJECTIVE In our study, we evaluated the potential of micro-CT for the assessment of the rat knee joint using ex vivo micro-CT arthrography. The aims of the study were to introduce the technique of micro-CT arthrography and to visualize the normal anatomy of the rat knee. The secondary aims were the quantification of retropatellar cartilage thickness and the analysis of microstructural cancello...

OBJECTIVE To determine the diagnostic accuracy of CT arthrography and virtual arthroscopy in the diagnosis of anterior cruciate ligament and meniscus pathology. MATERIALS AND METHODS Thirty-eight consecutive patients who underwent CT arthrography and arthroscopy of the knee were included in this study. The ages of the patients ranged from 19 to 52 years and all of the patients were male. Sagi...

The purpose of this review was to demonstrate magnetic resonance (MR) arthrography findings of anatomy, variants, and pathologic conditions of the superior glenohumeral ligament (SGHL). This review also demonstrates the applicability of a new MR arthrography sequence in the anterosuperior portion of the glenohumeral joint. The SGHL is a very important anatomical structure in the rotator interva...

OBJECTIVE To investigate the use of low-field magnetic resonance imaging (MRI) and MR arthrography in normal canine stifles and to compare MRI images to gross dissection. STUDY DESIGN Descriptive study. SAMPLE POPULATION Adult canine pelvic limbs (n=17). METHODS Stifle joints from 12 dogs were examined by orthopedic and radiographic examination, synovial fluid analysis, and MRI performed ...

BACKGROUND AND PURPOSE An acetabular labral tear is a diagnostic challenge. Various clinical tests have been described, but little is known about their diagnostic sensitivity and specificity. We investigated the diagnostic validity of clinical tests and ultrasound as compared with MR arthrography. PATIENTS AND METHODS We examined 18 patients (18 hips, 2 men, median age 43 (32-56) years) with ...

Objective: The study's primary objective is to compare the diagnostic efficacy of magnetic resonance (MR) arthrography, arthroscopy, and MDCT arthrography in preoperative planning anterior shoulder instability a larger cohort 100 patients.Topics Techniques: A total individuals (60 men 40 women, with mean age 29) underwent MR over course 11 months, beginning January 2021. imaging data were exami...

OBJECTIVE To prospectively investigate the healing process of meniscal repair with plain magnetic resonance imaging (MRI) and indirect MR arthrography and to compare the two methods. MATERIALS AND METHODS Twenty patients with an arthroscopic meniscal repair without clinical symptoms underwent conventional and indirect MR arthrography of the affected knee, 3, 6 and 12 months after the index op...
