Chosun University Hospital Introduces State-of-the-Art PET-CT Equipped with Artificial Intelligence

Reduction of Radiation Exposure Dose and Implementation of High-Resolution Imaging

[Asia Economy Honam Reporting Headquarters Reporter Yoon Jamin] Chosun University Hospital has introduced and is operating a high-resolution cutting-edge PET-CT equipped with artificial intelligence.

Chosun University Hospital (Director Jeong Jonghoon) announced on the 5th that it has newly introduced and started normal operation of the latest digital PET-CT from the American company GE, the 'Discovery MI DR' device.

The Discovery MI DR, introduced by the Department of Nuclear Medicine at Chosun University Hospital (Head Ha Jeongmin), is an imaging device that incorporates the latest functions of GE, such as Q.clear and artificial intelligence technology, characterized by its ability to produce high-resolution images while reducing radiation exposure.

PET-CT is a device that combines positron emission tomography (PET) and computed tomography (CT), capable of detecting small lesions about 2 mm in size, making it an excellent nuclear medicine device for early cancer diagnosis, metastasis detection, and monitoring treatment progress.

It is widely used not only for diagnosing various cancers but also for examining severe diseases that are major causes of death in Korea, such as brain diseases accompanied by dementia, Parkinson's syndrome, and verifying the effectiveness of cardiovascular surgery, allowing for precise measurement for treatment.

The newly introduced equipment has increased sensitivity to detect abnormal tissues by more than 60% compared to existing devices. The amount of radiopharmaceuticals injected into the patient's body has also been reduced by about 30%, thereby decreasing radiation exposure from the examination.

Using Q.clear and artificial intelligence technology, it can reduce image distortion caused by breathing and movement, and improve the overlap rate where image quality deteriorates as it moves away from the center of the image detector, enabling more accurate examinations and enhanced quantitative analysis functions. Additionally, the total examination time has been shortened.

Ha Jeongmin, head of the Department of Nuclear Medicine, said, "Since starting operation in 2005, Chosun University Hospital has conducted about 28,000 PET-CT examinations, and with the introduction of this latest PET-CT, we expect to provide the best medical service through more accurate quantitative analysis."
