To reevaluate idiopathic pulmonary fibrosis (IPF) cases which had surgical lung biopsy (SLB) for diagnosis of usual interstitial pneumonia (UIP), and examine the influence of computed tomography (CT) findings and clinical information based on diagnostic certainty. ⋯ In this retrospective series, some cases that had UIP confirmed on SLB for IPF diagnosis were classified into a low-level certainty group by expert chest radiologists and pulmonologists. When a diagnosis of IPF is made, the possibility of CHP, CTD-IP, and idiopathic NSIP must be also considered.

(1) To evaluate the ability of emergency room radiologists to detect acute mesenteric ischemia (AMI) from computed tomography (CT) images in patients with acute abdominal pain. (2) To identify factors affecting radiologists' performance in the CT interpretation and patient outcome. ⋯ AMI is underdiagnosed in the CT of the acute abdomen if there is no clinical suspicion.

Comparative Study
Differentiation of high-grade-astrocytomas from solitary-brain-metastases: Comparing diffusion kurtosis imaging and diffusion tensor imaging.
To compare the value of MRI diffusion kurtosis imaging (DKI) and diffusion tensor imaging (DTI) in differentiating high-grade-astrocytomas from solitary-brain-metastases. ⋯ DKI and directional analysis could lead to improved differentiation with better sensitivity and directional specificity than DTI.

To semi-quantitatively assess expiratory air trapping (AT(exp)) and structural changes in the proximal airways in asthma during asthma exacerbation (AE) and to explore the relationships among AT(exp), clinical indices, and proximal airway changes. ⋯ During AE, there was a high prevalence of extensive AT(exp) which was correlated with patient's age, BMI, BSA, AE severity and RB1 morphology but not correlated with BC(exp).
