It is concluded that nonionic contrast media significantly reduce the frequency of severe and potentially life-threatening ADRs to contrast media at all levels of risk and that use of these media represents the most effective means of increasing the safety of contrast media examinations.
Detectability of hypervascular hepatocellular carcinoma by arterial phase images of MR and spiral CT.
IA-spiral CT was the best for detecting hypervascular HCCs, and there was no significant difference in detectability in any tumor size between IV-MR imaging and IV-Spiral CT.
Evaluation of Tricuspid Regurgitation by Pulsed Doppler and Two‐dimensional Echocardiography
It is concluded that noninvasive grading of tricuspid regurgitation by ultrasonic pulsed Doppler and two-dimensional echocardiography is practicable.
Effects of spontaneous respiration on right and left ventricular function: evaluation by respiratory and ECG gated radionuclide ventriculography.
The results indicate that inspiratory reduction of LVSV during spontaneous respiration is due to a decrease in LVEDV which may be derived from an increase in RVEDV during inspiration through the mechanism of ventricular interdependence.

The authors describe the enhanced magnetic resonance (MR) imaging appearance of intrahepatic Cholangiocarcinoma, which shows various enhancement patterns, which depend on both the histologic subtype and the degree and distribution of flbrosis within the tumor.

The high sensitivity and high speed rotational acquisition capability of the SPECT device permits dynamic SPECT studies to be carried out in the analysis of rapidly varying radiotracer concentrations.
Assessment of the side-effects of iomeprol.
Interpretation of subtle interstitial chest abnormalities: Conventional radiography versus high-resolution storage-phosphor radiography—A preliminary study
The high-resolution storage-phosphor chest radiography (0.1-mm pixel size, 10-bit depth) may be substituted for conventional chest radiology in the detection of subtle interstitial abnormalities.
Left ventricular function in patients with coronary arteritis due to acute febrile mucocutaneous lymph node syndrome or related diseases.
Lung cancer: intermittent irradiation synchronized with respiratory motion--results of a pilot study.
Synchronized irradiation with the authors' system allowed convenient and reliable reduction of the target volume and was detectable with fast portal localization radiography.
