Observational Study
Diagnostic performance of CT and MRI in distinguishing intraductal papillary neoplasm of the bile duct from cholangiocarcinoma with intraductal papillary growth.
We aimed to evaluate the diagnostic performance of CT and MRI for distinguishing intraductal papillary neoplasm of the bile duct (IPNB) from cholangiocarcinoma (CC) with intraductal papillary growth (IPG). ⋯ • IPNB can accurately be identified by using defined diagnostic criteria at CT/MRI. • IPNB has some characteristic CT and MR imaging features. • IPNB is a rare entity; up until now it might have been misdiagnosed.

To evaluate the role of endovascular treatment for controlling haemorrhage in haemodynamically unstable patients with pelvic bone fractures and to relate clinical efficacy to pre-procedural variables. ⋯ • The series presented is one of the largest in a single centre. • Arterial embolisation is a life-saving procedure in patients with pelvic haemorrhage. • In pelvic traumas associated with haemorrhage, prognosis is dependent upon prompt treatment. • Transfusion status is significantly related to clinical efficacy.

To assess a radiologist's detection rate of rib fractures in trauma CT when reading curved planar reformats (CPRs) of the ribs compared to reading standard MPRs. ⋯ • In major blunt trauma, rib fractures are diagnosed with Computed Tomography. • Image processing can unfold all ribs into a single plane. • Unfolded ribs can be read twice as fast as axial images. • Unfolding the ribs allows a more accurate diagnosis of rib fractures.
