New Brain PET Scanner Corrects Blurring in Images Caused by Body Motion

Ordinary brain PET (positron emission tomography) scanners are unable to accurately measure the distribution of radiopharmaceuticals in the brain if the patients move their head during the examination process. As a result, a head holder is required to immobilize the patients although immobilizing the head for a long time can be unpleasant and uncomfortable. Now, a newly-developed brain PET scanner that does not require a head holder could solve this problem. Such a scanner can greatly benefit subjects with psychiatric disorders such as autism and hyperactivity who cannot manage to keep still, as well as help patients with moderate to severe dementia who are unable to maintain a constant resting state.

Hamamatsu Photonics (Shizuoka, Japan) has developed the HIAS-29000 brain PET scanner that corrects the blurring in PET images caused by body motion of the examined subject. The HIAS-29000 brain PET scanner with motion correction enables high-precision measurement of the brain state of subjects who find it difficult to keep still during the examination process. The novel brain PET scanner with motion correction is expected to pave the way for further research on achieving early detection and pathological elucidation of dementia and other psychiatric disorders.

Images in a 75-year-old woman who underwent routine screening mammography in 2022. Left mediolateral oblique views shown from prior screening mammograms: (A) 2015, (B) 2018, (C) 2019, and (D) 2021. In (E) 2022, a new mass developed in the left breast at the 6-o’clock position (arrow), with a (F) corresponding irregular mass at US (arrow). Subsequent US-guided core needle biopsy yielded invasive ductal carcinoma, grade 2. The deep learning 5-year risk scores gradually increased from 2.0 (2015) to 2.1 (2018), 3.4 (2019), 3.6 (2021), and 15.3 (2022).

$Image: Kyushu University researchers use Dynamic Chest Radiography (DCR) to evaluate the severity of Pulmonary Regurgitation (PR), a common complication after treatment of the congenital heart disease Tetralogy of Fallot. The analysis only requires the patient to hold their breath for seven seconds for a sequence of images of their heart to be taken. The images are then analyzed and extracted into a waveform that can show the severity of PR. The new technique\\\'s detection accuracy of severe PR is 93%, with a sensitivity of 93% and a specificity of 94%. (Photo courtesty of Kyushu University/Yuzo Yamasaki)$
