("Medicsight" or "the Company") 
 
 
Additional Information request for FDA 510(k) Clearance of 
ColonCAD software 
 
 
Medicsight PLC (AIM: MDST), industry leader in the development of Computer-Aided 
Detection (CAD) and image analysis software which assists radiologists in the 
early detection of disease, announces that on 5 January 2010 it received a 
further request for Additional Information (AI) letter from the US Food and Drug 
Administration (FDA) relating to the Company's currently pending 510(k) 
pre-market notification for the ColonCAD API 3.1 product. 
 
 
The FDA previously issued an AI letter to the Company in December, 2008 
requesting clarification of the intended use of the product, to which the 
Company responded. In the most recent AI letter the FDA has requested further 
technical details regarding the clinical trials and data analyses undertaken to 
support clearance of the product. 
 
 
FDA 510(k) submissions for Class 2 devices such as the current ColonCAD API 3.1 
submission are necessarily complex and require the sponsor company to provide a 
great deal of information relating to the design, manufacture and validation of 
the product. It is not unusual for a second AI request to be received by a 
company in order for the FDA to gain all the information they require in order 
to assess a device. However, the FDA's 510(k) process is typically restricted to 
two AI letters. 
 
 
Allan Rowley, CEO of Medicsight, said: "We are working expediently with our 
clinical and statistical advisors and the FDA to prepare the requested 
information and expect to respond fully to the FDA before the deadline of 21 
June 2010."

Notes to editors 
Medicsight PLC is a UK-headquartered, research driven, leading developer of 
computer-aided detection (CAD) and image analysis software for the medical 
imaging market. The CAD software automatically highlights suspicious areas on 
computerised tomography (CT) scans of the colon and lung, 
helping radiologists to identify, measure and analyse potential disease and 
early indicators of disease. Medicsight's CAD software has been developed using 
one of the world's largest and most population diverse databases of verified 
patient CT scan data. Medicsight's ColonCAD(TM) and LungCAD(TM) software 
products are seamlessly integrated with the advanced 3D visualisation 
workstations of several industry-leading imaging equipment partners. 
 
 
About Computer-Aided Detection 
With increasingly sophisticated radiological imaging hardware such as 
Multi-Detector CT scanners, radiologists are facing a growing challenge in the 
amount of detailed patient image data that they must review for each patient 
examination. Some CT scan examinations generate as many as 2000 images per 
patient. Review of this data by the radiologist is not only time-consuming but 
also prone to error due to reader fatigue. CAD software can help the reviewing 
radiologist by analysing the image data and automatically highlighting 
suspicious regions of interest for closer inspection. Without CAD software some 
potential abnormalities or areas of disease may be overlooked. This can 
be critical for diagnosis and the management of patient outcomes as early 
detection of disease greatly increases the probability of successful treatment 
and a positive therapeutic outcome. In addition to supporting individual 
radiologists CAD also has the potential to help standardise CT interpretation 
across both individuals and institutions thereby supporting population based 
screening programmes. 
 
 
 
 
About Medicsight's CAD software 
Medicsight's ColonCAD(TM) and LungCAD(TM) software use an advanced CAD algorithm 
to analyse CT scans of the colon and lung and automatically highlight suspicious 
areas that may be indicators of disease. CAD may highlight areas easily 
overlooked by the reviewing radiologist, such as small lesions or regions that 
are hidden from view behind folds in the colon or normal structures and 
surrounding tissue in the lung. 
 
 
Both CAD products seamlessly integrate with the advanced 3D visualisation 
platforms of industry-leading imaging equipment partners. The integrated systems 
provide sophisticated image viewing capabilities, including 3D reconstructed 
image data, with the added advantage of demonstrating automatic CAD findings to 
assist clinical end users in the detection and analysis of disease. This allows 
clinical end users to perform either a 'second read', where CAD findings are 
displayed to the user after completion of an initial review of the CT scan data, 
or a 'concurrent read' where CAD findings are displayed during the user's 
initial review of the original CT scan images. 
 
 
Since inception, Medicsight has developed close and lasting relationships with 
some of the world's foremost clinicians in product related areas. This provides 
the Company with a wealth of clinical expertise and dedicated clinical research 
to support ongoing product development. Medicsight also collaborates with a 
number of leading academic institutions and clinical research programmes 
worldwide to develop the Company's comprehensive database of population diverse 
verified patient CT scan data, thus allowing Medicsight's products to be 
validated to the highest possible standards.
