A comparison between histopathology and findings on magnetic resonance imaging of subcutaneous lipomatous soft-tissue tumors.

OBJECTIVE: To retrospectively analyse the magnetic resonance (MR) findings of subcutaneous lipomatous soft-tissue tumours (SLSTT) in order to define a diagnostic and therapeutic strategy. METHODS: The MR findings of 46 SLSTT were registered for the following data: area, location within the subcutaneous compartment, dimensions, shape and delineation, signal intensity (SI) on different pulse sequences, signal homogeneity, degree and pattern of contrast enhancement. The MR findings, together with patients' age and gender, were compared with histopathological findings.

How do referring clinicians want radiologists to report? Suggestions from the COVER survey.

OBJECTIVE: To investigate what referring clinicians suggest when asked how the quality of radiology reports can be improved. METHODS: At the end of the questionnaire of the COVER survey, a bi-national quantitative survey on the radiology report among referring physicians, clinical specialists and general practitioners were able to freely enter suggestions with regard to improving the quality of the report. These suggestions were isolated from the quantitative results.

Pseudotumoural soft tissue lesions of the hand and wrist: a pictorial review.

Mimickers of soft tissue tumours in the hand and wrist are more frequent than true neoplastic lesions. Pseudotumours belong to a large and heterogeneous group of disorders, varying from normal anatomical variants, cystic lesions, post-traumatic lesions, skin lesions, inflammatory and infectious lesions, non-neoplastic vascular lesions, metabolic disorders (crystal deposition disease and amyloidosis) and miscellaneous disorders. Although the imaging approach to pseudotumoural lesions is often very similar to the approach to "true" soft tissue tumoral counterparts, further management of these lesions is different.

Experience with a frontal core biopsy device in soft tissue and bone lesions.

Objective: To assess the efficacy and cost of a new frontloading biopsy system, Spirotome® (system 1), in musculoskeletal lesions, and to compare the results with those obtained with commonly used biopsy devices.

Methods: System 1 was used in all soft tissue lesions (STL) and osteolytic bone lesions (OBL) of patients who presented at our department for CT-guided biopsy between January 2009 and June 2010. Accuracy and cost were compared to those of Bonopty® (system 2) and Tru-cut (system 3) procedures.

The radiology report as seen by radiologists and referring clinicians: results of the COVER and ROVER surveys.

Purpose: To investigate and compare the opinions and expectations regarding the radiology report of radiologists and referring clinicians and to identify trends, discordance, and discontent.

Materials And Methods: A total of 3884 clinicians and 292 radiologists were invited by e-mail to participate in two internet surveys, COVER (for clinical specialists and general practitioners) and ROVER (for radiologists). Respondents were asked to state their level of agreement with 46 statements according to a Likert scale.

Soft tissue tumors: grading, staging, and tissue-specific diagnosis.

The value of medical imaging in detection, staging, grading, and tissue-specific diagnosis has been substantially increased, especially after the introduction of magnetic resonance imaging, the combined use of cytogenetic and molecular techniques and the refinement of biopsy techniques. In this paper, we will focus on the combination of parameters including clinical information, prevalence, age, location, and findings on medical imaging, yielding the highest diagnostic sensitivity and specificity. An imaging prototype of a malignant soft tissue tumor will be proposed.

Accuracy of MRI in characterization of soft tissue tumors and tumor-like lesions. A prospective study in 548 patients.

The purpose of our study was to assess prospectively the value of MRI in characterization of soft tissue tumors (STT) and soft tissue tumor-like lesions in a multi-institutional setting by a group of experts. The material consisted of 548 untreated and proven STT or tumor-like lesions originating from a multi-institutional database of STT in which 930 consecutive patients with STT examined by MRI were registered between 1 January 2001 and 28 April 2003. Based on MRI findings, a suitably ordered differential diagnosis was made in consensus by two radiologists (J.

The interutricular distance determined from external landmarks.

Knowledge of the exact distance between the utricles is important in new vestibular tests, such as the unilateral centrifugation (UC) test for the unilateral examination of the utricles. During this test, subjects are rotated at constant velocity and simultaneously laterally displaced along an interaural axis so that one labyrinth becomes aligned with the axis of rotation. When the axis of rotation crosses precisely through one labyrinth, only the opposite labyrinth is stimulated.

Van Buchem disease: lifetime evolution of radioclinical features.

Objective: The purpose of this study was to evaluate the lifetime evolution of the radioclinical features in a large family with van Buchem disease.

Design And Patients: The study population included 13 patients, ranging between 6 and 69 years. The evolution of the clinical features has been assessed by retrospective analysis of the clinical records of the patients.

Imaging features of musculoskeletal tuberculosis.

The purpose of this article is to review the imaging characteristics of musculoskeletal tuberculosis. Skeletal tuberculosis represents one-third of all cases of tuberculosis occurring in extrapulmonary sites. Hematogenous spread from a distant focus elsewhere in the body is the cornerstone in the understanding of imaging features of musculoskeletal tuberculosis.

Brainstem hemorrhage in descending transtentorial herniation (Duret hemorrhage).

Objectives: To review clinical and radiological findings in patients with Duret hemorrhages and to discuss the pathophysiology and differential diagnosis of these lesions.

Patients And Methods: We reviewed the case records of four patients with Duret hemorrhages who had been admitted to the neurological intensive care unit with supratentorial mass lesions.

Results: Descending transtentorial and subfalcine herniations were present in all cases.
