    • JULY 2004 RADIOLOGY UPDATE N otes f rom mensurate with these new recruits, the department has entered into a strategic research alliance with Siemens Medical to leverage and advance several mutual research the Chair interests. Further support for the department’s research enter- prise will be enabled by the acquisition of several dedi- cated research imaging systems. This year the installation of two MR research systems (a 1.5 Tesla and a 3 Tesla) Update on Research in into the MR Imaging Clinic is planned. The clinic is cur- rently undergoing extensive remodeling and expansion. In the Department of Radiology addition, two 16-slice research CT scanners will support research in computed tomography. The first 16-slice CT scanner has been installed in the Iowa Comprehensive Lung Imaging Center. The second CT scanner will reside in the department and will be dedicated to supporting clini- cal CT research. Renovations for the new PET Center are well underway; the center will include two PET-CT systems, as well as a PET system dedicated to research. Aside from the “human” imaging systems for research, the department has been enormously successful in gar- nering support for several animal imaging systems, including two micro CT systems, a bioluminescence CT system, a micro PET system, and several other nuclear medicine instruments (gamma camera, 3 headed SPECT system and a PET system for larger animals). These instruments form the basis for a complete small animal imaging facil- Laurie L. Fajardo, MD ity now being planned by the College of Medicine.

CTA has been utilized in attempting to evaluate various vascular pathologies. In the near future, CTA will replace many conventional diagnostic angiographic exams. Diagnostic value of CTA is comparable to contrast enhanced 3D mag- netic resonance angiography (MRA). However, it should be stressed that CTA is faster and cheaper than MRA, and better at evaluating small vessels. In addition, MRA can be operator dependent and requires patient coopera- tion (e.g. holding breath).

In abdominal imaging, the act of cre- ating 3D images should be paired with interpretation. Al- though axial images may be sufficient for diagnosis in most cases, it is best to make the most of high quality multiplanar reformation capabilities (as well as source images), which will ultimately increase the confidence level of interpreta- tion. The abdominal imaging applications of MDCT are not only used for CTA. For example, CT urography (CTU) is a valuable and simple modality for the workup of a patient with hematuria, producing clearer images of renal tumor, stone, and lesions outside of the GU system. CTU can be a single and complete modality of choice, and the total cost and radiation dose of CTU should be compared to those of other diagnostic modalities, since multiple studies are oc- casionally needed for diagnosis. CTU (Targeted MIP image) shows normal collecting systems and ureters. Bladder stones are present. 4
