In Observance of U.S. Holiday, Memorial Day, Agilent Cross Lab/ iLab Operations Software Support Help Desk will be closed during U.S. hours on Monday May 27th, 2019. We will resume regular U.S. support hours on Tuesday May 28th, 2019. EU and APAC Support will remain open during this time. For urgent matters, please add "Urgent" to the ticket/ email subject or press "1", when prompted, to escalate a call on the iLab Support phone and we will prioritize those requests first.

HMRI PET Imaging Core


Please follow this link to go to the Houston Methodist Research Institute [PET Imaging] site for detailed information about the core.


Our center houses a state-of-the-art Philips Gemini TF PET/CT machine. This high performance machine associates a PET scan with LYSO crystals, whose resolution at the center of the field of view is 4.8 mm, to a 64-slice CT scan. Time-of-Flight technology provides a better image quality by reducing noise. It also improves sensitivity, especially for whole-body scans.
We provide a wide array of 18F- and 11C-labeled radiotracers, as well as the methodological expertise to perform kinetic modeling, image processing, and dosimetric calculations.
Our center can also perform fully quantitative PET scans by measuring the metabolite-corrected arterial plasma input function.



The Philips Precedence SPECT/CT machine associates a multislice CT with a flexible dual-headed gamma camera.
The machine is equipped with low to medium energy high-resolution collimators, suited for most diagnostic radioisotopes.
Images can be acquired in both planar and tomographic mode, with both static and dynamic frames.
