TL;DR: The results show that a distinction is needed between small-, medium-, and large-field CBCT scanners and protocols, as they are applied to different indication groups, the dose received being strongly related to field size.

TL;DR: A simple qualitative MRI Crohn's disease activity score appears predictive against a histopathological standard of reference.

TL;DR: Shear wave elastography is a reliable and reproducible noninvasive method for the assessment of liver elasticity and expert operator had higher reproducibility of measurements over time than novice operator.

TL;DR: No significant difference in diagnostic accuracy for the non-invasive assessment of liver fibrosis was found for transient elastography and ARFI, Nevertheless TE significantly correlated with liver Fibrosis while ARFI did not.

TL;DR: The results indicate that the proposed morpho-functional MR-scoring-system is reproducible and applicable for semi-quantitative evaluation of a large spectrum of CF lung disease severity.

TL;DR: The published scientific literature was reviewed to collect information regarding effective dose levels during the most common CT examinations in adults and paediatrics and the justification principle is discussed along with tools that assist clinicians in the decision-making process.

TL;DR: ARFI elastography is a reliable method for predicting fibrosis severity in chronic hepatitis C patients and TE was better than ARFI for predicting the presence of liver cirrhosis and fibrosis (F ≥ 1, METAVIR) (p=0.01).

TL;DR: The increased functional connectivity of the amygdala with the premotor and sensorimotor cortex demonstrates a compensatory mechanism to overcome the negative effects of sleep deficits and maintain the psychomotor performances in PI patients.

TL;DR: Intra-individual comparisons between SDCT and LDCT suggest that AIDR 3D allows a 64.2% reduction of the radiation dose as compared to SDCT, by substantially reducing the objective image noise and increasing the SNR, while maintaining the overall diagnostic acceptability.

TL;DR: DECT is able to identify pulmonary perfusion defects with good accuracy and may potentially enhance the diagnostic accuracy in the assessment of PE.

TL;DR: This review focuses on the main clinical applications and accuracy of PET/CT for the detection of non-small cells lung cancer, broncho-alveolar carcinoma (BAC), small cells Lung cancer (SCLC), lung neuroendocrine tumours (NET) and solitary pulmonary nodules (SPN).

TL;DR: (18)FDG-PET-CT has higher diagnostic value (sensitivity, specificity and DORs) for diagnosing bone metastasis from lung cancer than any other imaging methods.

TL;DR: The diagnostic accuracy of combined 1HMRSI-DCEMR was higher than PET/CT to identify local prostate cancer recurrence, mostly in patients with low biochemical progression after radical retropubic prostatectomy.

TL;DR: Second-generation dual-energy CT based VNC images provide attenuation values close to those of TNC, and multiple measurements are recommended especially for measurements in the spleen, the mesenteric fat, and the aorta.

TL;DR: The 66 kPa threshold in Shear Wave elastography is the best ultrasound sign to rule out malignant thyroid nodules and the method is simple, quantitative, reproducible and usable in the study of nodules larger than 3 cm.

TL;DR: Compared to MRI and SPECT both, dynamic real-time perfusion CT and first-pass dual-energy perfusions CT showed good agreement for the detection of myocardial perfusion defects.

TL;DR: It is suggested that ultrasound and radiology screening methods be used to confirm DDH in newborns that present with one or a combination of the following common risk factors: breech presentation, female, left hip affected, first born and family history of DDH.

TL;DR: The study suggested that abnormality of GMD in right DLPFC might be related to the functional connectivity alteration in the pathophysiology of MDD, which might be useful in further characterizing structure-function relations in this disorder.

TL;DR: FDG-PET or FDG- PET/CT is more accurate than CT and MR imaging in the detection of lymph node metastasis in patients with ovarian cancer.

TL;DR: A meta-analysis to asses the overall risk of CIN, chronic loss of kidney function and the need for renal replacement therapy (RRT) after intravenous contrast enhanced CT-scan and to identify subgroups at increased risk for CIN.

TL;DR: Automated breast volume scanner provides advantages of high diagnostic accuracy, better lesion size prediction, operator-independence and visualization of the whole breast, and is a promising modality in breast imaging.

TL;DR: VSM is a visualization tool for the supply chain and value stream, based on the Toyota Production System and greatly assists in successfully implementing a Lean system.

TL;DR: Using MBIR improved image quality, reduced image noise and increased CNR as compared to the other available reconstruction techniques, which may further improve the visualization of coronary artery plaque and allow radiation reduction.

TL;DR: Dual energy spectral CT imaging has higher sensitivity in preoperative diagnosis of insulinomas compared with conventional MDCT, and the combination of monochromatic image and iodine density image can improve the diagnostic sensitivity of insulinoma.

TL;DR: The diagnostic accuracy of FDG PET or PET/CT is good in metastatic lesions of urinary bladder cancer.

TL;DR: It is suggested that hypoxia in medulla is more apparent and earlier than in cortex in diabetes, and MCR increased in early stage of diabetes and decreased along with the aggravation of diabetic nephropathy.

TL;DR: C-choline PET/CT showed a better sensitivity than BS in patients with biochemical relapse after RP in prostate cancer patients, and detected unknown bone lesions in 18/123 patients.

TL;DR: The results suggest that the positive culture rate of percutaneous spinal biopsy specimens is 30.4% with radiographically high probability for infection, which is lower than previously published.

TL;DR: Compared with standard dose C TCA using FBP, low dose CTCA using SAFIRE can maintain diagnostic image quality with 50% reduction of radiation dose, according to a comparison of image quality and radiation dose in obese patients.

TL;DR: Calculating the ADC value is useful for distinguishing lymphoma from glioblastoma and a better inverse correspondence with tumor cellularity were obtained with ADC(MIN) at b-4000 s/mm(2) at 3T MRI.
