Whole-body diffusion magnetic resonance imaging with simultaneous multi-slice excitation in children and adolescents. Pediatr Radiol 2023; 53:1485-1496. [PMID: 36920515 PMCID: PMC10276081 DOI: 10.1007/s00247-023-05622-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/21/2022] [Revised: 01/27/2023] [Accepted: 01/30/2023] [Indexed: 03/16/2023]
Abstract
BACKGROUND Whole-body magnetic resonance imaging (WB-MRI) is an increasingly used guideline-based imaging modality for oncological and non-oncological pathologies during childhood and adolescence. While diffusion-weighted imaging (DWI), a part of WB-MRI, enhances image interpretation and improves sensitivity, it also requires the longest acquisition time during a typical WB-MRI scan protocol. Interleaved short tau inversion recovery (STIR) DWI with simultaneous multi-slice (SMS) acquisition is an effective way to speed up examinations. OBJECTIVE In this study of children and adolescents, we compared the acquisition time, image quality, signal-to-noise ratio (SNR) and apparent diffusion coefficient (ADC) values of an interleaved STIR SMS-DWI sequence with a standard non-accelerated DWI sequence for WB-MRI. MATERIALS AND METHODS Twenty children and adolescents (mean age: 13.9 years) who received two WB-MRI scans at a maximum interval of 18 months, consisting of either standard DWI or SMS-DWI MRI, respectively, were included. For quantitative evaluation, the signal-to-noise ratio (SNR) was determined for b800 images and ADC maps of seven anatomical regions. Image quality evaluation was independently performed by two experienced paediatric radiologists using a 5-point Likert scale. The measurement time per slice stack, pause between measurements including shim and total measurement time of DWI for standard DWI and SMS-DWI were extracted directly from the scan data. RESULTS When including the shim duration, the acquisition time for SMS-DWI was 43% faster than for standard DWI. Qualitatively, the scores of SMS-DWI were higher in six locations in the b800 images and four locations in the ADC maps. There was substantial agreement between both readers, with a Cohen's kappa of 0.75. Quantitatively, the SNR in the b800 images and the ADC maps did not differ significantly from one another. CONCLUSION Whole body-MRI with SMS-DWI provided equivalent image quality and reduced the acquisition time almost by half compared to the standard WB-DWI protocol.

Abstract
Depending on the age and location within the skeleton, bone marrow can be mostly fatty or hematopoietic, and both types can be affected by marrow necrosis. This review article highlights the magnetic resonance imaging findings of disorders in which marrow necrosis is the dominant feature.Fatty marrow necrosis is detected on T1-weighted images that show an early and specific finding: the reactive interface. Collapse is a frequent complication of epiphyseal necrosis and detected on fat-suppressed fluid-sensitive sequences or using conventional radiographs. Nonfatty marrow necrosis is less frequently diagnosed. It is poorly visible on T1-weighted images, and it is detected on fat-suppressed fluid-sensitive images or by the lack of enhancement after contrast injection.Pathologies historically "misnamed" as osteonecrosis but do not share the same histologic or imaging features of marrow necrosis are also highlighted.

Abstract
Several infections can predispose to certain malignancies in different body parts. These infections include viral, bacterial, and fungal pathogens. Imaging plays a vital role in the diagnosis, staging, and management of these neoplastic conditions. Furthermore, it can help in differentiating infection-related non-neoplastic processes that can mimic malignancies. Both radiologists and clinicians should be familiar with these conditions. This review discusses the epidemiology, pathogenesis, and imaging features of infection-related tumors.

Abstract
Whole-body magnetic resonance imaging (MRI) is increasingly being used for a number of indications. Our aim was to review and describe indications and scan protocols for diagnostic value of whole-body MRI for multifocal disease in children and adolescents, we conducted a systematic search in Medline, Embase and Cochrane for all published papers until November 2018. Relevant subject headings and free text words were used for the following concepts: 1) whole-body, 2) magnetic resonance imaging and 3) child and/or adolescent. Included were papers in English with a relevant study design that reported on the use and/or findings from whole-body MRI examinations in children and adolescents. This review includes 54 of 1,609 papers identified from literature searches. Chronic nonbacterial osteomyelitis, lymphoma and metastasis were the most frequent indications for performing a whole-body MRI. The typical protocol included a coronal STIR (short tau inversion recovery) sequence with or without a coronal T1-weighted sequence. Numerous studies lacked sufficient data for calculating images resolution and only a few studies reported the acquired voxel volume, making it impossible for others to reproduce the protocol/images. Only a minority of the included papers assessed reliability tests and none of the studies documented whether the use of whole-body MRI affected mortality and/or morbidity. Our systematic review confirms significant variability of technique and the lack of proven validity of MRI findings. The information could potentially be used to boost attempts towards standardization of technique, reporting and guidelines development.

Abstract
PURPOSE OF THE REVIEW To provide a clinically useful literature review on the rheumatic manifestations of haemoglobinopathies, critically analysing the literature from the past 5 years. RECENT FINDINGS There are limited new data to guide the management of rheumatic manifestations of haemoglobinopathies. Data further confirm the wide spectrum of potential rheumatic/MSK involvement in haemoglobinopathies, which poses both a diagnostic and therapeutic challenge. Inflammatory arthritis may be more common than previously believed. Steroid therapy by any route of administration can provocate a potential life-threatening vaso-occlusive crisis. Vitamin D deficiency is common. There are limited data to guide the drug treatment of reduced bone density in haemoglobinopathies. There have been a number of studies examining pain in sickle cell anaemia. Plasma levels of Klotho may represent a novel biomarker in patients with β-Thalassemia. There are little new data on the rheumatic manifestations in haemoglobinopathies and future high-quality research is needed.

Abstract
The haemoglobinopathies are a relatively common, heterogeneous group of inherited conditions that are the result of either a quantitative abnormality (e.g. thalassaemia) or structural [e.g. sickle cell anaemia (SCA)] of the globin part of the haemoglobin molecule. Musculoskeletal (MSK) complications are common in patients with haemoglobinopathies and may affect the whole of the MSK system, in addition to bone, which is the primary site of the disease. Typical MSK complications include painful vaso-occlusive disease and osteomyelitis in SCA and reduced BMD in thalassaemia. Patients may also develop a number of related (e.g. gout) or unrelated rheumatic diseases (e.g. inflammatory arthritis and autoimmune CTDs). Treatment of MSK conditions in patients with haemoglobinopathies may be challenging (e.g. bone marrow suppression from disease-modifying agents) and in particular in SCA, steroid therapy (by any route) may precipitate potentially severe vaso-occlusive complications. Rheumatologists need to be aware of the range of MSK complications, treatment challenges and the need for such patients to be managed as part of a dedicated multidisciplinary team alongside haematology.
