Proceedings of the Joint Meeting RBRS Bone Section and Nederlandse Vereniging Voor Skeletaradiologie, Leiden, The Netherlands, 25.0.3.2011-Part II. Tumors and tumorlike conditions of the calcaneous: the usual and the unusual.

The calcaneus is an uncommon site for involvement by tumors or tumorlike conditions of bone, although any lesion may involve the calcaneus. The purpose of this paper is to highlight the imaging features of common and uncommon tumors and tumorlike conditions occurring in the calcaneus. Typical case studies will illustrate the imaging findings on different imaging modalities.

Structured reporting: if, why, when, how-and at what expense? Results of a focus group meeting of radiology professionals from eight countries.

Purpose: To determine why, despite growing evidence that radiologists and referring physicians prefer structured reporting (SR) to free text (FT) reporting, SR has not been widely adopted in most radiology departments.

Methods: A focus group was formed consisting of 11 radiology professionals from eight countries. Eight topics were submitted for discussion.

Grading and characterization of soft tissue tumors on magnetic resonance imaging: the value of an expert second opinion report.

Objective: To retrospectively compare the accuracy of the initial MRI (magnetic resonance imaging) report of referring radiologists and the second opinion report.

Material And Methods: MRI of 155 patients presenting with a soft tissue tumor (STT) in a single large community center were referred for inclusion in the Belgian Soft Tissue Neoplasm Registry (BSTNR). The initial report and the second opinion report were made independently.

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 foot and ankle: a pictorial review.

In the foot and ankle region, benign neoplasms and pseudotumoural soft tissue lesions are significantly more frequent than malignant tumours. The pseudotumoural lesions constitute a heterogeneous group, with highly varied aetiology and histopathology. This article reviews the imaging features of the most common pseudotumours of the soft tissues in the foot and ankle.

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.

Magnetic resonance imaging in teenagers and young adults with limited haemophilic arthropathy: baseline results from a prospective study.

The clinical relevance of subtle changes on magnetic resonance imaging (MRI) for evaluating haemophilia treatment is unknown. To determine the relationship of findings on MRI with joint function and bleeding in joints with apparently very mild arthropathy, a prospective study was performed. Knees and ankles of 26 patients, 13-26 years, were scanned.

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.

Ewing's sarcoma: imaging features.

Aim: To define an imaging prototype of Ewing's sarcoma (ES).

Materials And Methods: Sixty-four patients with a histopathologically and/or genetically proven diagnosis of ES were analyzed for clinical parameters (age, gender and location), radiographic and CT appearance (distribution, matrix, margins, periosteal reaction, articular extension, cortical reaction and the presence of a pathologic fracture). Size, local extension, signal intensity, degree and pattern of enhancement, and the presence of skip metastases were evaluated on MRI.
