Multicenter Study
Inter-observer agreement for the evaluation of bone involvement on Whole Body Low Dose Computed Tomography (WBLDCT) in Multiple Myeloma (MM).
We aimed to assess inter-observer agreement in bone involvement evaluation and define accuracy and reproducibility of MDCT images analysis in Multiple Myeloma (MM), by comparing two acquisition protocols at two different institutions. ⋯ • MDCT represents a reproducible technique for defining bone disease in MM. • Overall inter-observer agreement is good, even when comparing two different protocols. • Influence of readers' experience on image analysis is partial.

To investigate long-term pain reduction and 'improvement' in patients with indirect cervical nerve-root-blocks in comparison to MRI findings. ⋯ • Good long term outcomes after indirect nerve root infiltrations with non-particulate steroids. • The presence of nerve root compression was a predictive finding of 'improvement'. • Significantly less patients subsequently having surgery had lower NRS scores 1-month post injection. • There is less pain relief in patients with disc extrusions. • There are less improvement in patients with modic type I changes.

Non-simple nodules in hepatocellular carcinoma (HCC) correlate with poor prognosis. Therefore, we examined the diagnostic ability of gadolinium-ethoxybenzyl-diethylenetriamine pentaacetic acid-enhanced magnetic resonance imaging (EOB-MRI) and contrast-enhanced ultrasound (CEUS) for diagnosing the macroscopic classification of small HCCs. ⋯ • Non-SN has a higher frequency of MVI and intrahepatic metastasis than SN. • Macroscopic classification is useful to choose the treatment strategy for small HCCs. • Diagnostic ability for macroscopic findings of EOB-MRI and CEUS were statistically equal. • The diagnosis of macroscopic findings by individual modality has limitations. • Combined diagnosis of EOB-MRI and CEUS provides high diagnostic ability.

Alzheimer's disease (AD) and frontotemporal (FTD) dementia can be differentiated using [(18)F]-2-deoxy-2-fluoro-D-glucose (FDG)-PET. Since cerebral blood flow (CBF) is related to glucose metabolism, our aim was to investigate the extent of overlap of abnormalities between AD and FTD. ⋯ • Similar patterns of hypoperfusion and hypometabolism were observed in patients with dementia. • For both imaging modalities, parietal abnormalities were found in Alzheimer's disease. • For both imaging modalities, prefrontal abnormalities were found in frontotemporal dementia.

Multidetector computed tomography (CT) plays an important role in the detection, risk stratification and prognosis evaluation of acute pulmonary embolism. This review will discuss the technical improvements for imaging peripheral pulmonary arteries, the methods of assessing pulmonary embolism severity based on CT findings, a multidetector CT technique for pulmonary embolism detection, and lastly, how to avoid overutilization of CT pulmonary angiography and overdiagnosis of pulmonary embolism. Key Points • We describe clinical prediction rules and D-dimers for pulmonary embolism evaluation. • Overutilization of CT pulmonary angiography and overdiagnosis of pulmonary embolism should be avoided. • We discuss technical improvements for imaging peripheral pulmonary arteries. • Pulmonary embolism severity can be assessed based on CT findings. • We discuss multidetector CT techniques for pulmonary embolism detection.
