“…A few studies have investigated MB or SMS in free-breathing whole-body DWI: Buus et al [ 24 ] found that MB reduced acquisition time for free-breathing whole-body DWIBS by 48 % while maintaining a similar subjective image quality at 1.5 T in breast cancer patients.…”

“…We did not investigate the variation of ADC, but Larsen et al [ 25 ] found that free-breathing and respiratory compensation produced fairly identical ADC-values in standard DWI. In addition, Buus et al [ 24 ] found that ADC-values were similar in DWIBS with and without MB.…”

“…Whole-body SMS-DWI was recently used for bone metastases screening in PCa and showed similar image quality compared to standard DWI. 91 Deep learning methods for image reconstruction are also emerging, which will further reduce DWI sequence acquisition times. These methods are still not widely available, and their impact on WB-MRI use cannot yet be evaluated.…”

Over the past decade, updated definitions for the different stages of prostate cancer and risk for distant disease, along with the advent of new therapies, have remarkably changed the management of patients. The two expectations from imaging are accurate staging and appropriate assessment of disease response to therapies. Modern, next-generation imaging (NGI) modalities, including whole-body magnetic resonance imaging (WB-MRI) and nuclear medicine (most often prostate-specific membrane antigen [PSMA] positron emission tomography [PET]/computed tomography [CT]) bring added value to these imaging tasks. WB-MRI has proven its superiority over bone scintigraphy (BS) and CT for the detection of distant metastasis, also providing reliable evaluations of disease response to treatment. Comparison of the effectiveness of WB-MRI and molecular nuclear imaging techniques with regard to indications and the definition of their respective/complementary roles in clinical practice is ongoing. This paper illustrates the evolution of WB-MRI imaging protocols, defines the current state-of-the art, and highlights the latest developments and future challenges. The paper presents and discusses WB-MRI indications in the care pathway of men with prostate cancer in specific key situations: response assessment of metastatic disease, "all in one" cancer staging, and oligometastatic disease.

“…One possibility of sequence acceleration is the simultaneous excitation and readout of multiple slices (SMS) by exploiting the different spatial sensitivity profiles of multi-coil arrays [ 16 , 17 ]. This technique has already been established for MRI [ 18 ], and its advantages have been outlined in various studies on different organ systems, such as the liver [ 19 ], breast [ 20 ] and skeletal system [ 21 ], but mainly in adult patients. Kenkel et al showed both a drastic reduction in the duration of whole-body MRI using SMS-DWI and its clinical applicability in adults [ 22 ].…”

Whole-body diffusion magnetic resonance imaging with simultaneous multi-slice excitation in children and adolescents

et al. 2023

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.
