Our customers say...
“The experience of using Biograph Horizon PET/CT equipment has been very rewarding. In addition to the excellent quality of images provided by the technology, we have been able to conduct examinations offering lower doses of radiation to patients and, at the same time, faster acquisitions.”2
MD, Nuclear Medicine Director
Brasilia, Brazil
“We are now routinely conducting 12-15 PET/CT scans per day, compared to 6 scans in the past with our previous PET/CT”2
Kyoto Prefectural University of Medicine (KPUM)
Kyoto, Japan
“Not only did Biograph Horizon answer all our needs in terms of cost effectiveness and quality control, it also improved our daily practice with high-resolution images and great sensitivity.”2
Nuclear Medicine Physicist
Brasilia, Brazil
“The AI features allow us to focus on a specific task, which usually is the patient. You want to spend time with them to make sure they're OK and that they are getting the best solution they need for treatment.”2

6-mm lymph node detectability in prostate cancer using ultraHD•PET and 4-mm crystals.
ultra•HD PET allows excellent detection of 6-mm lymph node. 4-mm crystal size results in good image quality with 68Ga tracer.

Case 1
Distinction of gyri and sulci due to excellent spatial resolution afforded by 4-mm crystal size.
4-mm crystal size illustrates good separation of gyri and sulci. Decreased crystal size also results in detailed contrast between white and gray matter.

Case 2
Time of flight (TOF) imaging allows high-quality myocardial perfusion imaging in obese patient (82 BMI).
With true TOF, activity is more localized and results in improved spatial resolution and thus improves image quality in particularly obese patients.

Case 3
Dynamic multi-pass whole-body PET using FlowMotion to help define suspicious abdominal uptake as physiological.
Focal uptake in the abdomen is likely to be confused with retroperitoneal lymph node metastases in a patient with advanced rectal cancer with multiple pelvic nodal metastases.
Dynamic whole-body PET/CT as a routine acquisition procedure defines focal uptake as physiological tracer retention in the ureter due to a slight decrease in uptake over 4 dynamic passes, typical of physiological uptake, which varies due to peristalsis or fluid transit.
