The aim of this study was to evaluate the accuracy and applicability of solitarily reading fused image series of T2-weighted and high-b-value diffusion-weighted sequences for lesion characterization as compared to sequential or combined image analysis of these unenhanced sequences and to contrast- enhanced breast MRI. ⋯ • Unenhanced breast MRI with additional DWIBS/T2w-image fusion allows reliable lesion characterization. • Abbreviated reading of fused DWIBS/T2w-images alone decreases diagnostic confidence and accuracy. • Reading fused DWIBS/T2w-images as the sole diagnostic method should be avoided.

To assess the added-value of systematic unenhanced abdominal computed tomography (CT) on emergency department (ED) diagnosis and management accuracy compared to current practice, in elderly patients with non-traumatic acute abdominal symptoms. ⋯ • Systematic unenhanced CT improves significantly diagnosis accuracy compared to current practice. • Systematic unenhanced CT optimizes appropriate hospitalization by increasing the number of discharged patients. • Systematic unenhanced CT allows detection of about one-third of acute unsuspected abdominal conditions. • It should allow boosting emergency department management decision-making confidence in old patients.

Comparative Study
Fine-needle aspiration versus core needle biopsy for diagnosis of thyroid malignancy and neoplasm: a matched cohort study.
To compare the diagnostic performances of fine-needle aspiration (FNA) and core needle biopsy (CNB) in the diagnosis of thyroid malignancy and neoplasm in patients who underwent surgery for thyroid nodules. ⋯ • Diagnostic performances of FNA and CNB for thyroid malignancy and neoplasm were compared. • FNA showed comparable performances to CNB both before and after statistical matching. • There may be no benefit in performing CNB, given the comparable performances.

Comparative Study
Grading diffuse gliomas without intense contrast enhancement by amide proton transfer MR imaging: comparisons with diffusion- and perfusion-weighted imaging.
To investigate whether amide proton transfer (APT) MR imaging can differentiate high-grade gliomas (HGGs) from low-grade gliomas (LGGs) among gliomas without intense contrast enhancement (CE). ⋯ • Amide proton transfer (APT) imaging helps in grading non-enhancing gliomas • High-grade gliomas showed higher APT signal than low-grade gliomas • APT imaging showed better diagnostic performance than diffusion- and perfusion-weighted imaging.
