Kidney tumor ablation treats nonsurgical candidatesOver 35,000 new cases of renal cell carcinoma occurred in the U.S. in 2001,1 most of them detected as incidental imaging findings on CT, MR, or ultrasound.2,3 Since most of these tumors are relatively small when detected, the classic clinical triad of flank pain, hematuria, and palpable mass is now rarely encountered. Many of these incidentally discovered RCCs are also slow growing. Bosniak et al showed that RCCs smaller than or equal to 3.5 cm grow at an average rate of 0 to 1.1 cm/year (mean 0.36 cm/year).4

‘Molecular switch’ protein protects heart from damageA single amino acid substitution in a cardiac muscle protein improved cardiac function in mice and in damaged human heart cells. This amino acid could be the key to a new gene or cell-based therapy for cardiovascular disease, according to a study published online Jan. 22 in Nature Medicine.

Ultrasonographic Screening for Fetal MalformationsAs the risk for fetal malformation is present in all pregnant women, many experts believe that prenatal ultrasound screening should be universal. The frequency of fetal malformations and the undesirable consequences for affected infants and their families are convincing arguments for using this modality on a routine basis.

Analysis teases out true value of outsourcing anytime readsThe need for nighttime coverage relief was the initial driver of commercially viable teleradiology. For several years, however, the local in-house radiology group gained no economic value for outsourcing its nighttime work, because its members had to reread the cases the next day to formally convert the reports to primary reads. The group also had to pay a premium for nighttime services.

FDG-PET takes lead role in suspected or proven infectionIn recent years, several groups have demonstrated the promise of FDG-PET imaging in the management of patients with suspected and/or documented infection. This technique appears to be particularly useful in the evaluation of osteomyelitis, infected prostheses, fever of unknown origin, and acquired immunodeficiency syndrome. Considering the extraordinary sensitivity of FDG-PET in detecting disease activity and nonactivity in malignant and benign disorders, this powerful method may prove valuable also in a variety of infectious processes. We speculate that it will be widely employed in the near future for detecting, characterizing, and monitoring patients with suspected or proven infection.

MR imaging evaluates ulcerative colitis casesAdvances in MR technology have improved the quality of abdominal MRI and hence the ability to assess intestinal diseases. Rapid acquisition sequences have reduced the incidence of motion artifacts from intestinal peristalsis, while the use of phased-array coils has increased spatial resolution. Several intestinal contrast agents have undergone extensive trials. Meanwhile, the use of sequences that modulate MRI signal selectively, for example by suppressing fat tissue signal, can improve gadolinium-related enhancement on T1-weighted images, as well as boosting T2 signal in pathologic tissues.

Routine body perfusion CT approaches clinical realityThe most crucial process to assess in a tumor for efficient management is neo-angiogenesis. Currently, no reliable biomarker is available to measure angiogenesis, and direct microvessel density assay requires frequent biopsies for serial tumor monitoring. Technological innovations in imaging, however, have enabled the capture of physiological information in addition to anatomic details. One promising imaging technique for acquiring physiological information about angiogenesis is perfusion CT, which provides anatomic information as well.
