PET/CT cranks it up a notch with new advances
CT is the hare and PET the tortoise in the imaging world. In a hybrid scanner, however, neither can win without the other. Little wonder engineers have put so much effort into speeding up the PET portion.
CT is the hare and PET the tortoise in the imaging world. In a hybrid scanner, however, neither can win without the other. Little wonder engineers have put so much effort into speeding up the PET portion.
Over the past few years, much of the technological emphasis has focused on boosting detector efficiency with crystals that register data more quickly, thereby reducing the time needed for an exam or enhancing image quality. This approach has given way in the last year to other developments:
- Detectors packed with more crystals boost the number of photons detected over a set period, or electronics and software that home in on each positron annihilation, increasing the resolution of the PET camera.
- Software speeds image registration and reconstruction with not just faster computing but smarter ways to process the data. Included are ways to handle what would otherwise result in a misregistration of the data sets.
- Algorithms correct artifacts caused by respiration or physical movement of the patient, which is most likely to occur during the PET scan.
- Novel ways compare and contrast images. PET/CT is as much about monitoring patient response to therapy as it is making the initial assessment. Smart ways to fetch and present data make the interpreter more effective.
Can Portable Dual-Energy X-Ray be a Viable Alternative to CT in the ICU?
September 13th 2024The use of a portable dual-energy X-ray detector in the ICU at one community hospital reportedly facilitated a 37.5 percent decrease in chest CT exams in comparison to the previous three months, according to research presented at the American Society of Emergency Radiology (ASER) meeting in Washington, D.C.
New Meta-Analysis Examines MRI Assessment for Treatment of Esophageal Cancer
September 12th 2024Diffusion-weighted MRI provided pooled sensitivity and specificity rates of 82 percent and 81 percent respectively for gauging patient response to concurrent chemoradiotherapy for esophageal cancer, according to new meta-analysis.
Study for Emerging PET/CT Agent Reveals ‘New Standard’ for Detecting Clear Cell Renal Cell Carcinoma
September 11th 2024Results from a multicenter phase 3 trial showed that the PET/CT imaging agent (89Zr)Zr-girentuximab had an 85.5 percent mean sensitivity rate for the diagnosis of clear cell renal cell carcinoma.
Can Radiomics and Autoencoders Enhance Real-Time Ultrasound Detection of Breast Cancer?
September 10th 2024Developed with breast ultrasound data from nearly 1,200 women, a model with mixed radiomic and autoencoder features had a 90 percent AUC for diagnosing breast cancer, according to new research.
