In vivo diffusion MRI of the human heart using a 300 mT/m gradient system
CONCLUSION: This work demonstrates cardiac DWI in vivo with higher b-value and higher order of motion compensated diffusion gradient waveforms than is commonly used. Increasing the motion compensation order from M 2 $$ {M}_2 $$ to M 3 $$ {M}_3 $$ and the maximum b-value from 450 to 1000 s / mm 2 $$ \mathrm{s}/{\mathrm{mm}}^2 $$ affected the MD values but FA and the angular metrics (HA and E2A) remained unchanged. Our work paves the way for cardiac DWI on the next-generation MR scanners with high-performance gradient systems.PMID:38650395 | DOI:10.1002/mrm.30118 (Source: Magnetic Resonance in Medicine)

"The least significant change on bone mineral density scan increased in patients with higher degrees of obesity"
CONCLUSION: LSC of 0.05 g/cm² could be used in clinical practice in patients with class 2 or 3 obesity. These findings should help to improve the interpretation of BMD scans in these patients and optimize their management.TRIAL REGISTRATION NUMBER: Comité de Protection des Personnes Ile-de France VII, France.PMID:38652346 | PMC:PMC11039528 | DOI:10.1007/s40520-024-02736-4 (Source: Aging Clinical and Experimental Research)

Assessing current clinical eruption stage of mandibular third molars by dental panoramic radiography
CONCLUSION: All teeth below or at the CE junction are clinically unerupted. Above the CE junction, stage of eruption should be assessed together with the inclination, but horizontally inclined teeth are recommended to be verified clinically.PMID:38651519 | DOI:10.2340/aos.v83.40477 (Source: Acta Odontologica Scandinavica)

Radio-Guided Surgery with a New-Generation β-Probe for Radiolabeled Somatostatin Analog, in Patients with Small Intestinal Neuroendocrine Tumors
CONCLUSION: This study reports optimal accuracy in detecting lesions of SI-NETs using the intraoperative RGS approach with a novel β-probe. The method was found to be safe, feasible, and easily reproducible in daily clinical practice, with minimal radiation exposure for the staff. RGS might potentially improve radical resection rates in SI-NETs.CLINICAL TRIALS REGISTRATION: 68Ga-DOTATOC Radio-Guided Surgery with β-Probe in GEP-NET (RGS GEP-NET) [NCT0544815; https://classic.CLINICALTRIALS: gov/ct2/show/NCT05448157 ].PMID:38652200 | DOI:10.1245/s10434-024-15277-x (Source: Ann Oncol)

Economic and healthcare resource utilization assessments of pet imaging in coronary artery disease diagnosis: a systematic review and discussion of opportunities for future economic evaluations
Conclusions: This SLR identified economic and HCRU evaluations following PET- and SPECT-MPI for CAD diagnosis and determined that existing studies do not capture all pertinent outcome parameters or link diagnostic performance to downstream HCRU and cardiac outcomes, thus, resulting in simplified assessments of CAD burden. A limitation of this work relates to heterogeneity in study designs, patient populations, and follow-up times of existing studies. Resultingly, it was challenging to pool data in meta-analyses. Overall, this work provides a foundation for the development of comprehensive economic models for PET- and SPECT...
