Abstract INTRODUCTION: MRI has a high sensitivity in determining changes in bone marrow induced by metastatic disease or primary neoplasms of the bone marrow. Whole-Body Magnetic Resonance Imaging (WB-MRI) is a novel imaging technique that displays nearly the complete skeletal system in one exam. We investigated the differences between conventional skeletal survey and WB-MRI and their impact on staging of patients with newly diagnosed plasma cell disease. METHOD AND MATERIALS: In 41 consecutive patients with newly diagnosed MGUS (n=5), Multiple Myeloma (n=34) or AL-Amyloidosis (n=2) conventional radiographs and WB-MRI (coronar T1 tse and T2 tirm sequences and sagittal T2 star sequences, 1,5 T MRI with parallel imaging, Siemens Avanto®) were performed. Radiographs and scans were evaluated for diffuse and focal bone marrow involvement in consent by two experienced radiologists blinded for patient name and study time. Staging was performed including clinical data according to the Salmon/Durie classification system and the Durie/Salmon PLUS classification system with inclusion of WB-MRI. RESULTS: In 24 (59%) patients there were no lesions in conventional radiography or MRI. In 17 (41 %) patients results of MRI and conventional radiography were discrepant. 4 (10%) patients had lesions only in MRI, 3 (7%) only in conventional radiography and 10 (24%) in both techniques but in different localization. In 16 (38%) patients with radiological signs of osteopenia there was no diffuse infiltration in MRI or vice versa. We systematically analysed the consequences of WB-MRI on staging of patients based on the newly proposed staging system Durie/Salmon PLUS. Replacing conventional radiographs by WB-MRI resulted in reclassification of 12 patients. 3 patients were reclassified from MGUS or stage I into stage II or III. 9 patients were downstaged from stage III or II into stage I or MGUS. CONCLUSION: WB-MRI is a valuable technique for the initial work-up of patients with Multiple Myeloma. In comparison with conventional skeletal survey there are often differing results with impact on clinical staging and influence on therapy decision. WB-MRI can give additional information in patients with unclear staging situation before onset of therapy. Further evaluation of WB-MRI within prospective studies is warranted in particular with respect to prognostic impact regarding overall prognosis as well as regarding local complications. Until then WB-MRI should be used complementary to conventional radiography or CT-techniques that provide accurate imaging of the bone.

AbstractObjectives:To compare the use of computed tomography – positron emission tomography and whole-body magnetic resonance imaging for the staging of head and neck cancer.Patients and methods:From January to July 2009, 15 consecutive head and neck cancer patients (11 men and four women; mean age 59 years; age range 19 to 81 years) underwent computed tomography – positron emission tomography and whole-body magnetic resonance imaging for pre-therapeutic evaluation. All scans were staged, as per the American Joint Committee on Cancer tumour–node–metastasis classification, by two blinded consultant radiologists, in two sittings. Diagnoses were confirmed by histopathological examination of endoscopic biopsies, and in some cases whole surgical specimens.Results:Tumour staging showed a 74 per cent concordance, node staging an 80 per cent concordance and metastasis staging a 100 per cent concordance, comparing the two imaging modalities.Conclusion:This study found radiological staging discordance between the two imaging modalities. Whole-body magnetic resonance imaging is an emerging staging modality with superior visualisation of metastatic disease, which does not require exposure to ionising radiation.

Abstract Bone disease is the most frequent feature of multiple myeloma (MM) and represents a marker of end-organ damage; it is used to establish the diagnosis and to dictate the immediate need for therapy. For this reason, imaging plays a significant role in the management of MM patients. Although conventional radiography has traditionally been the standard imaging modality, its low sensitivity in detecting osteolytic lesions and inability to evaluate response to therapy has called for the use of more sophisticated techniques, such as whole-body low-dose computed tomography (WBLDCT), whole-body magnetic resonance imaging, and 18F-fluorodeoxyglucose–positron emission tomography/computed tomography (PET/CT). In this review, the advantages, indications of use, and applications of the 3 techniques in the management of patients with MM in different settings will be discussed. The European Myeloma Network and the European Society for Medical Oncology guidelines have recommended WBLDCT as the imaging modality of choice for the initial assessment of MM-related lytic bone lesions. Magnetic resonance imaging is the gold-standard imaging modality for detection of bone marrow involvement, whereas PET/CT provides valuable prognostic data and is the preferred technique for assessment of response to therapy. Standardization of most of the techniques is ongoing.

AbstractMyeloma-associated bone disease (MBD) develops in about 80–90% of patients and severely affects their quality of life, as it accounts for the majority of mortality and morbidity. Imaging in multiple myeloma (MM) and MBD is of utmost importance in order to detect bone and bone marrow lesions as well as extraosseous soft-tissue masses and complications before the initiation of treatment. It is required for determination of the stage of disease and aids in the assessment of treatment response. Whole-body low-dose computed tomography (WBLDCT) is the key modality to establish the initial diagnosis of MM and is now recommended as reference standard procedure for the detection of lytic destruction in MBD. In contrast, whole-body magnetic resonance imaging (WBMRI) has higher sensitivity for the detection of focal and diffuse plasma cell infiltration patterns of the bone marrow and identifies them prior to osteolytic destruction. It is recommended for the evaluation of spinal and vertebral lesions, while functional, diffusion-weighted MRI (DWI-MRI) is a promising tool for the assessment of treatment response. This review addresses the current improvements and limitations of WBCT and WBMRI for diagnosis and staging in MM, underlining the fact that both modalities offer complementary information. It further summarizes the corresponding radiological findings and novel technological aspects of both modalities.
