Prediction of antenatal bleeding and preterm deliveries using placental magnetic resonance imaging in patients with placenta previa
ConclusionSubacute hematoma on placental MRI was associated with antenatal bleeding, emergency CS and shorter GA at delivery in patients with PP. Marginal hematoma was also associated with antenatal bleeding and emergency CS. Placental MRI appears useful for predicting antenatal bleeding and preterm delivery in patients with PP.

Diagnostic approach with Z-score mapping to reduce artifacts caused by cerebral atrophy in regional CBF assessment of mild cognitive impairment (MCI) and Alzheimer's disease by [99mTc]-ECD and SPECT
ConclusionThe proposed approach provided more preciseZ-scores with less over- or underestimation, artifacts, and improved diagnostic accuracy, being recommended for clinical studies. (Source: Japanese Journal of Radiology)

Combined visual and quantitative assessment of somatostatin receptor scintigraphy for staging and restaging of neuroendocrine tumors
ConclusionWe adapted the SUV to SRS and established the range of SUV for physiological uptake in the liver, kidney, and spleen. Combined visual and quantitative assessment is useful for imaging individual lesions in greater detail, and may serve as a new tumor marker of SRS for staging and restaging of NETs.

Exploration of tumor size measurement methods in preoperative breast cancer assessment using whole-body silicon photomultiplier PET: feasibility and first results
ConclusionsThe study demonstrated that among various PET thresholds, the '1.5 SUVmean  + 2 SD' threshold exhibited the best performance. However, even with this threshold, the concordance rate was limited to only 63%. (Source: Japanese Journal of Radiology)

Clinical value of [18F]AlF-NOTA-FAPI-04 PET/CT for assessing early-stage liver fibrosis in adult liver transplantation recipients compared with chronic HBV patients
Conclusion[18F]AlF-NOTA-FAPI-04 PET/CT could be applied to evaluate early-stage liver fibrosis in  LT recipients and CHB patients properly, with the potential additional advantages in monitoring and predicting complications after LT. (Source: Japanese Journal of Radiology)

Dual-energy computed tomography for evaluating nodal staging in lung adenocarcinoma: correlation with surgical pathology
ConclusionsFor lung adenocarcinoma, the quantitative measurement of NICmuscle derived from DECT is useful for differentiating benign and metastatic mediastinal and hilar LNs before surgical intervention. (Source: Japanese Journal of Radiology)

Multimodality imaging in cerebral venous thrombosis: a synopsis for emergency radiologist
AbstractCerebral venous thrombosis (CVT) is an uncommon but potentially fatal condition which presents with a wide range of symptoms. Some of these presenting features are vague thus contributing to the delay in diagnosis. A prompt diagnosis and initiation of appropriate therapy are therefore of paramount importance. In this pictorial, we have tried to illustrate the direct and indirect imaging features of CVT in detail on multiple imaging modalities, along with the potential pitfalls of imaging.

Retrospective case –control study examining the relationship between recurrence-free survival and changes in pre- and post-radioiodine therapy serum thyroglobulin levels in patients with differentiated thyroid cancer
ConclusionsChanges in thyroglobulin levels pre- and post-therapy were associated with RFS. Patients with decreased post-therapy thyroglobulin levels had a favorable prognosis, even if their thyroglobulin levels were positive after RAI therapy. (Source: Japanese Journal of Radiology)

Growth speed of large brain metastases between diagnostic and radiosurgical planning MRI and predictors of rapid tumor growth
ConclusionLarge brain metastases can grow considerably between the time of diagnosis and the time of fSRS treatment planning. We recommend the time between dMRI and fSRS treatment initiation be as short as possible. (Source: Japanese Journal of Radiology)
