Dr. Roman joined the Department of Radiology
and have been establishing a physiological and molecular imaging
laboratory. The laboratory’s approach is to combine modern
physiological and molecular biological techniques with imaging
modalities. There are two main areas of research in the laboratory
which are NIH supported; using magnetic resonance to detect gene
expression in the heart and the development of magnetic resonance
techniques for imaging pancreatic beta cell and islet function.
In order to successfully conduct this
research, the laboratory requires an array of equipment which is
unique to a Radiology department and provides us the ability to
conduct studies ranging from the single cell to the whole animal. The
laboratory has a cell culture facility consisting of a biosafety hood,
cell incubator, centrifuges, and a Zeiss fluorescence microscope. The
biochemistry lab is equipped with a high speed centrifuge,
quantitative real-time PCR machine, UV spectrophotometers, a
microplate reader, and a gel documentation and analysis system along
with associated electrophoresis equipment. The animal physiology
laboratory is equipped to perform microsurgery with the aid of a Zeiss
surgical microscope, associated rodent ventilator and anesthesia
machine. In vivo hemodyamic measurements are made in mice using a 1.4F
Millar pressure/volume transducer which is inserted into the mouse
ventricle and data digitized and analyzed in real time. This is not
trivial as the mouse heart is only 120 mg with a heart rate of 600-700
The primary imaging modality used is magnetic
resonance, both spectroscopy and imaging. We currently utilize the
4.7T animal scanner located in the magnetic resonance imaging and
spectroscopy laboratory headed by Dr. Greg Karczmar for all in vivo
cardiac and pancreatic imaging. Cellular imaging studies of isolated
rodent and human pancreatic islets are conducted on a 11.7T scanner
located at the University of Illinois at Chicago (see image below). We
are looking forward to the acquisition of a 9.4T animal scanner which
will allow us conduct molecular imaging studies not possible on our
