HI, I'm a college student studying radiology. 
I find interventional radiology to be interesting. It help with imaging. 
Yes, it is so interesting to be able to see what is happening inside the body and to help guide treatment options. 
Walter A. Wohlgemuth became famous because of his work in radiology with kids.
I did not know that.  Tell me more about his work.
He focused on congenital vascular anomalies. 
Oh wow. So important. Who are some other famous radiologists?
Cutis marmorata telangiectatica congenita
Cutis marmorata telangiectatica congenita is a rare congenital vascular disorder that usually manifests in affecting the blood vessels of the skin. The condition was first recognised and described in 1922 by Cato van Lohuizen, a Dutch pediatrician whose name was later adopted in the other common name used to describe the condition – Van Lohuizen Syndrome. CMTC is also used synonymously with congenital generalized phlebectasia, nevus vascularis reticularis, congenital phlebectasia, livedo telangiectatica, congenital livedo reticularis and Van Lohuizen syndrome.
It should not be confused with the
Interventional oncology
Interventional oncology (abbreviated IO) is a subspecialty field of interventional radiology that deals with the diagnosis and treatment of cancer and cancer-related problems using targeted minimally invasive procedures performed under image guidance. Interventional oncology has developed to a separate pillar of modern oncology and it employs X-ray, ultrasound, computed tomography (CT) or magnetic resonance imaging (MRI) to help guide miniaturized instruments (e.g. biopsy needles, ablation electrodes, intravascular catheters) to allow targeted and precise treatment of solid tumours (also known
