The aim of this research is to see how many cannabinoid receptors (CB1R) are present in the human brain. CB1R are located in the brains of all people, regardless of whether or not they have used cannabis. The researchers will use PET imaging and the radioligand OMAR to visualize brain cannabinoid receptors in healthy people and people with various conditions such as 1) cannabis use disorders, 2) psychotic disorders, 3) prodrome of psychotic illness, 4) people with a family history of alcoholism, and 5) people with Post-Traumatic Stress Disorder. 6) Opioid Use Disorder using [11C]OMAR as a PET imaging agent or radiotracer. We’ll be able to describe the number and distribution of CB1R in these conditions as a result of this. Following the collection of pilot data and as new information on cannabinoid receptor activity and psychiatric disorders becomes accessible, the list of conditions is likely to be extended.
The participants in the cannabis use disorder arm of the study will have a PET scan at least three times: once while smoking as normal, once after 48 hours of cannabis abstinence, and once after four weeks of cannabis abstinence. Additional scans can be done within the next four weeks, and the final scan may be done much later. Similarly, although the majority of schizophrenia patients will only be screened once, a subset of patients may be scanned several times. Unmedicated patients, for example, can be scanned when unmedicated and again after treatment with antipsychotic drugs to tease out the effects of medications. Prodromes can also be scanned when in the prodromal stage, when on drugs, and after conversion to schizophrenia.

PET scanning is a form of diagnostic imaging. PET imaging is a technique that allows the body’s biologic functions to be imaged. PET scans can detect areas of irregular glucose metabolism in the body by using a small amount of a biological marker.
A change in metabolism may be detected before a physical change is detected on a CT or MRI scan. The new imaging breakthrough blends a PET scan with a CT scan (PET/CT), allowing areas of interest to be more precisely located.
When booking a PET scan, bear in mind that your doctor may require you to adhere to a strict PET scan preparation diet for up to 12 hours prior to your appointment. The following is a standard PET scan diet:
Medicare and private insurance providers typically cover PET/CT imaging. Although private insurance generally meets Medicare requirements, many will cover a PET/CT scan for other purposes. For more details, contact your insurance company.

Does anyone have a good response for me? I’m in desperate need of details. I’m not going to ask my doctor because I think they don’t do it if I haven’t had one. They, referring to both my MO and my surgeon. However, my surgeon prescribed a slew of other examinations.
My first PET scan will take place today. I presume it was only requested because my CT scans in March and June showed a substantial difference. I’ve never had an MRI before, and I’m hoping it won’t be my next experience. I’m still surprised at how different docs use different exams. It may also be calculated by the policies of various insurance firms. If you’re unsure about something, don’t be afraid to ask your doctor. I haven’t had the PET yet, but I’m not fond of it so far because I was advised to avoid sugar, caffeine, and carbs of any kind 24 hours before the test and to eat nothing for 6 hours beforehand. So, I’m hungry and lacking my morning coke. Also, they don’t seem to have the facilities to do PET scans in as many locations as they do CT scans, so I’ll have to drive to Ft. Worth, which is enough to make me nervous. Please accept my apologies if I provided too much detail.
