Science to Practice:

Scott O. Trerotola: Can Combination Therapy for Colorectal Liver Metastases Improve Results over Chemoembolization or Ablation Alone?
Their study suggests, as does previously published evidence for hepatoma, that better outcomes can be achieved with combination, rather than individual, therapy techniques.

Jeffrey A. Cooper: Responsible Conduct of Radiology Research Part IV. The Boundary of Research and Practice
Since the boundaries of research and innovative care or quality improvement often are not clear, when activities are or become human research, thus becoming subject to Department of Health and Human Services or Food and Drug Administration regulations, they must be reviewed and approved by an institutional review board.

We conclude that there is a high prevalence (86%) of reported findings with whole-body CT screening and that most are benign by description; however, 37% of patients receive recommendations for follow-up examinations, most frequently for findings in the lungs and the kidneys.

Because at least 99% of all nodules 4 mm or smaller are benign and because such small opacities are extremely common on thin-section CT scans, we do not recommend follow-up CT in every such case; in selected cases with suspicious morphology or in high-risk subjects, a single follow-up scan in 12 months should be considered.

Marie Staunton, Jonathan D. Dodd, Peter Aiden McCormick, and Dermot E. Malone: Finding Evidence-based Answers to Practical Questions in Radiology: Which Patients with Inoperable Hepatocellular Carcinoma Will Survive Longer after Transarterial Chemoembolization?
Evidence-based practice techniques were used to establish which patients with inoperable hepatocellular carcinoma will survive longer when they are treated with transarterial chemoembolization alone; the results indicate that only those who meet the inclusion criteria used in two randomized controlled trials published in 2002 should receive this treatment.

Taken together, our results on cells in culture show that there appears to be a dependence between heat-induced DNA damage, cell survival, and temperature and that a narrow temperature threshold leading to irreparable DNA damage should be considered for adequate tumor elimination.

As we have shown, the well-known enhancement patterns of hepatocellular carcinoma (HCC) at gadolinium-enhanced dynamic T1-weighted MR imaging cannot be readily transferred to ferucarbotran-enhanced imaging, because the same HCC lesion may display different enhancement patterns when the vascular phases of these contrast agents are directly compared.

As compared with the use of digital subtraction angiography as the initial imaging test, the use of multi–detector row CT angiography as the initial imaging test for the evaluation of peripheral arterial disease yields sufficient information for decision making; reduces imaging costs; leads to similar costs for therapy, hospital stays, and outpatient visits; and leads to similar degrees of quality-of-life improvement.

As compared with digital subtraction angiography, 16–detector row CT angiography has excellent diagnostic accuracy in the assessment of lower-leg peripheral arterial disease, provided that the thinnest possible section width is used.

For proper object-specific attenuation correction of cardiac SPECT images, we recommend SPECT/CT image registration based on internal landmarks and on CT images acquired either with free breathing or with breath holding after normal exhalation.

Arkadiusz Sitek and Robert G. Sheiman: Small-Bowel Perfusion Measurement: Feasibility with Single-Compartment Kinetic Model Applied to Dynamic Contrast-enhanced CT
Our data indicate that small-bowel time-enhancement curves can be constructed by using motion-corrected CT images, and, more important, that small-bowel perfusion parameters can be measured by using these corrected contrast-enhanced CT images.

Because at least 99% of all nodules 4 mm or smaller are benign and because such small opacities are extremely common on thin-section CT scans, we do not recommend follow-up CT in every such case; in selected cases with suspicious morphology or in high-risk subjects, a single follow-up scan in 12 months should be considered.
