Radiation dose and excess risk of cancer in children undergoing neuroangiography.
The primary goal of this study was to determine the radiation dose received during diagnostic and interventional neuroangiographic procedures in a group of pediatric patients. A second goal was to approximate the total average radiation dose from all angiographic and CT studies that pediatric patients underwent during the study period and to estimate the increased risk of cancer incidence in this patient group. ⋯ Although both angiography and CT have revolutionized the practice of medicine and confer benefits to patients, it is important that we continue to investigate the possible adverse effects of these technologies. Protocols that minimize radiation dose without compromising a study should be implemented.

MRI of soft-tissue tumors: fast STIR sequence as substitute for T1-weighted fat-suppressed contrast-enhanced spin-echo sequence.
The purpose of this study was to assess the value of the fast STIR sequence in comparison with the T1-weighted fat-suppressed contrast-enhanced sequence in the evaluation of soft-tissue tumors. ⋯ The fast STIR sequence is excellent for evaluation of soft-tissue tumors, and contrast-enhancement is not always needed.

Triple-drug transcatheter arterial chemoembolization in unresectable hepatocellular carcinoma: assessment of survival in 124 consecutive patients.
The objective of our study was to describe survival outcome in 124 patients with unresectable hepatocellular carcinoma treated with triple-drug transcatheter arterial chemoembolization (TACE) using doxorubicin, cisplatin, and mitomycin C using a standardized regimen. ⋯ Patients with hepatocellular carcinoma who underwent triple-drug TACE followed by liver transplantation showed the longest survival. Patients who did not receive a transplant and were treated with triple-drug TACE with a permanent embolic agent showed longer survival to 30 months after TACE than those receiving a nonpermanent embolic agent.

Evaluation of the C1-C2 articulation on MDCT in healthy children and young adults.
We aimed to establish normal values on MDCT images for the atlantoaxial relationships including the atlantoaxial interval and lateral atlantodens interval (ADI) that could be used to detect atlantoaxial ligamentous injuries in adults and children. ⋯ We propose that the obtained normal values be considered as the upper limits of the normal range for the atlantoaxial interval in adult and pediatric populations on MDCT images.
