A cross-comparative analysis of in vivo versus ex vivo MRI indices in a mouse model of concussion
CONCLUSION: Our findings call for caution in extrapolating translational capabilities obtained ex vivo to physiological measurements in vivo. The divergent findings may reflect fixation artefacts and the contribution of the glymphatic system changes.PMID:37673379 | DOI:10.1016/j.brainres.2023.148562

Continuous time-resolved estimated synthetic 4D-CTs for dose reconstruction of lung tumor treatments at a 0.35 T MR-linac
Phys Med Biol. 2023 Sep 5. doi: 10.1088/1361-6560/acf6f0. Online ahead of print.ABSTRACTTo experimentally validate a method to create continuous time-resolved estimated synthetic 4D-computed tomography datasets (tresCTs) based on orthogonal cine MRI data for lung cancer treatments at a magnetic resonance imaging (MRI)-guided linear accelerator (MR-linac).
Approach. A breathing porcine lung phantom was scanned at a CT scanner and 0.35 T MR-linac. Orthogonal cine MRI series (sagittal/coronal orientation) at 7.3 Hz, intersecting tumor-mimicking gelatin nodules, were deformably registered to mid-exhale 3D-CT and 3D-MRI...

Functional assessment in endometrial and cervical cancer: diffusion and perfusion, two captivating tools for radiologists
Eur Rev Med Pharmacol Sci. 2023 Aug;27(16):7793-7810. doi: 10.26355/eurrev_202308_33435.ABSTRACTUterine cervical and endometrial cancers are two major gynecological malignancies, affecting women's health worldwide. Magnetic resonance imaging (MRI) is appropriate for evaluating malignant disease, thanks to the excellent soft tissue contrast and multiplanar imaging ability. Recently, functional MR techniques, namely diffusion-weighted imaging (DWI) and dynamic contrast-enhanced imaging (DCE), have proved to be a precious support not only in cancer diagnosis but also in disease staging, in the therapy planning, in monitoring ...

Diagnostic value of MRI radiomics in differentiating high ‑grade glioma from low‑grade glioma: A meta‑analysis
Oncol Lett. 2023 Aug 23;26(4):436. doi: 10.3892/ol.2023.14023. eCollection 2023 Oct.ABSTRACTNo clear conclusions have yet been reached regarding the accuracy of magnetic resonance imaging (MRI) radiomics in distinguishing high-grade glioma (HGG) from low-grade glioma (LGG). In the present study, a meta-analysis was conducted to determine the diagnostic value of MRI radiomics in differentiating between HGG and LGG, in order to guide their clinical diagnosis. PubMed, Embase and the Cochrane Library databases were searched up to November 2022. The search included studies in which true positive, false positive, true negative a...

Anti-SOX-1 Antibody-Positive Paraneoplastic Limbic Encephalitis Diagnosed During Small Cell Lung Cancer Treatment
We present a case of anti-Sry-like high mobility group box 1 (SOX-1) antibody-positive PNS diagnosed during the treatment of small-cell lung cancer (SCLC). A 65-year-old woman with a history of smoking and SCLC (T3N1M0) was hospitalized to receive chemo-radiation therapy. On day 14, the course was complicated by left mastitis associated with febrile neutropenia. Drainage was performed for the left mastitis, and cefepime was initiated. The fever subsided within a few days, but the patient became agitated accompanied by logorrhea. With the exception of mental status, her neurological examination was unremarkable. Due to mild...
