FAQ Section

Q: What’s the difference between 16-slice and 64-slice PET-CT?
A: 64-slice scanners provide faster scanning and better resolution for cardiac imaging, while 16-slice models are sufficient for standard oncology applications.

Q: Which brand offers the best PET-CT for oncology?
A: Siemens Biograph Vision and GE Discovery MI are considered top choices for oncology imaging due to their high sensitivity and resolution.

Q: Are there any total-body PET-CT scanners available?
A: Yes, United Imaging’s uEXPLORER is the first commercial total-body PET-CT scanner, offering unprecedented sensitivity.

Q: What’s the advantage of digital PET-CT technology?
A: Digital PET (like Philips Vereos) provides better image quality and lower radiation dose compared to conventional analog systems.

Q: How much does a 64-slice PET-CT machine cost?
A: Prices range from 1.5Mto1.5Mto2.5M depending on the brand and configuration.
