Imaging modality for the CV-imaging project:

Coronary angiography:

1. Done on the chest area, the probe rotates around the chest of the subject, but there is no such a thing as "chest Coronary angiography", it is simply called Coronary angiography.
2. Creates images of the entire coronary artery system.
3. We don't record PRLOC = chest for this procedure

Thransthoracic Echocardiogram (TTE):

1. Done on the chest and upper abdominal wall. The transducer is placed on various parts of the chest and upper belly to get different views of the heart. Again, there is no such a thing as chest TTE.
2. Creates images of the heart.
3. We don't record PRLOC = Chest and upper abdomen for this procedure

Transesophageal Echocardiogram (TEE):

1. Done from the inside of the Esophagus.
2. Creates images of the heart.
3. We don't record PRLOC = Esophagus

Cine Angiography:

1. Done on the chest, again the probe is placed on top of the chest.
2. Creates images of the entire coronary artery system.

If we don't record the location for the procedures above, i,e, PRTRT = Coronary angiography, PRLOC = Chest, then why do chest and abdomen go into PRLOC for chest and abdominal CT scans?

In addition, I just took my mother to have a Thyroid Ultrasound:

1. The ultrasound probe moved around her neck
2. Creates images of the thyroid gland. In this case would you argue that PRLOC is thyroid or neck?

Referring to Richard's email:

LOC in the interventions class is "Anatomical focus of an intervention - at which part of the body an intervention is being made". This also my understanding as well.

• The "injection" intervention has an anatomical focus - the anatomical site of injection.
• Percutaneous Coronary Intervention (also known as angioplasty with stent), has an anatomical location where the procedure occurs, intervenes and alters the structure of the location - i.e. RIGHT POSTERIOR DESCENDING ARTERY

It is easy to pinpoint a location for invasive/treatment type interventions and this aligns with my understanding of how PRLOC should be used.

However, for "diagnostic imaging" procedures, where the imaging probe is placed (i.e. neck, chest, abdomen, head, etc.), is it relevant to record this information? Is this the location where the intervention is made? is it even correct to place these values in PRLOC?

so...my 2-cents is that diagnostic imaging procedures have no PRLOCs.

When we say "chest CT", it A chest CT doesn't mean that a CT is done on the chest, it is a CT scan of the chest,  it creates images of the chest, more precisely the thoracic region. If PRTRT = CT Scan, PRLOC = Chest. The way I read this is that the CT scan is done on the chest, which doesn't make sense.An abdominal CT doesn't mean a CT done on the abdomen, it is a CT scan of the abdomen, it creates images of the abdominal region"Chest" is the anatomical location for subsequent evaluations, aka --LOC for --TEST in a findings domain.

Same for abdominal and pelvic CT scans, MRIs.

Have I lose my god damn mind????
