Teleradiology Market Potential

"TechNavio, the market intelligence platform of Infiniti Research published its a new research report on the teleradiology market. The report says that the global market for teleradiology was around $6 billion in 2008, and is expected to grow at double digit rates in the next five years. The report says that “Technological advances and requirement to lower the healthcare costs have encouraged the healthcare services providers to outsource the diagnosis of radiology images to developing and low-cost countries. Also, the ease of entry for the new entrants in the teleradiology market has resulted in a higher competition in the market, and a greater number of teleradiology service providers.”

Symptomatic Bipartite Patella- MRI & CT

It is a common congenital fragmentation or synchondrosis of the patella. It occurs in approximately 1% of population but some have observed a much higher incidence; most remain asymptomatic, but direct trauma may disrupt the synchondroses, causing symtoms that mimic those of fracture. Symptomatic cases are identified on MRI with marrow edema as in our case of a 11 yr old with pain for last 6 months. Second opinion- Teleradiology Providers

Suspected Artery of Percheron Infarct-Rare Case Report

Thalami and midbrain arterial supply arises from many perforating blood vessels with a complex distribution for which many variations have been described. One rare variation, named the “artery of Percheron,” is a solitary arterial trunk that arises from one of the proximal
segments of a posterior cerebral artery and supplies the paramedian thalami and the rostral midbrain bilaterally. Occlusion of this artery results in bilateral thalamic and mesencephalic infarctions. This is a 50 year old female who developed sudden altered sensorium following hypotension due to sorbitrate administration. Similar cases have been described in AJNR Am J Neuroradiol 24:2005–2008, November/December 2003. Diffusion and FLAIR images of the case have been provided showing FLAIR hyperintensity and differential bright signal on DWI.

Aortic Dissection-CTA

"Much has been written on the subject of aortic dissections, from the first well-documented case of aortic dissection, when King George II of England died while straining on the commode, to the first successful operative repairs by DeBakey in 1955, to modern techniques of diagnosing and repairing thoracic aortic dissections. More recently, this has come to light with the diagnosis of aortic dissection in Princess Diana, actor John Ritter, and Dr. DeBakey himself. "
This is a case of spontaneous Stanford Type A & Debakey Type I aortic dissection with involvement of the ascending and descending aorta along with aortic root involvement, diagnosed on CT angiography.

Caroticocavernous Fistula-MRI

The caroticocavernous fistula is a specific type of dural arteriovenous fistula characterized by abnormal arteriovenous shunting within the cavernous sinus. A caroticocavernous fistula results in high-pressure arterial blood entering the low-pressure venous cavernous sinus.
This interferes with normal venous drainage patterns and compromises blood flow within the cavernous sinus and the orbit. This is post RTA case with caroticocavernous fistula on the right side diagnosed on MR angiography.
