Can the Newer Model of Breast-Specific Positron Emission Tomography Reduce the "Blind Area"?
Diagnostics (Basel)
September 2024
: Breast-specific positron emission tomography (PET) provides higher sensitivity and spatial resolution than whole-body PET/CT, but it has a blind area. Mammary glands near the chest wall sometimes present outside the field of view (FOV). A newer, dedicated breast PET (dbPET) model has a cylindrical detector with a larger diameter than previous models, so it is expected to eliminate or reduce blind areas.

- The study aimed to evaluate how compressed sensing (CS) with deep learning reconstruction (DLR) can enhance the quality of liver imaging compared to traditional methods.
- Seventy-seven patients with liver lesions were analyzed using both high-resolution contrast-enhanced T1-weighted imaging (HR-CE-T1WI) and conventional methods to assess image quality, clarity, and lesion detection rates.
- Results showed that HR-CE-T1WI had significantly better image quality and sensitivity for detecting liver lesions while reducing the likelihood of false positives.
Article Synopsis
- An area-detector CT (ADCT) features a 320-detector row that collects isotropic volume data across a 160 mm area without needing helical scanning, useful for assessing perfusion in nodules, lymph nodes, or tumors.
- The ADCT system allows both helical and alternative scanning methods, enabling advanced imaging for body structures and potential dual-energy imaging for enhanced visualization using various contrast agents.
- This review discusses recent advancements in ADCT including methods for reducing radiation doses, evaluating pulmonary morphology, perfusion, ventilation, and biomechanical properties.
