Online course for aesthetic injectors and the radiologists they call

Imaging the Filler Complication

What each filler looks like on ultrasound, MRI, CT and PET, how to work up a nodule or a vascular event with imaging, and which study to order for which question. Taught by a fellowship-trained radiologist who also injects.

Hyaluronic acid filler. Well-marginated, hypoechoic to anechoic, pseudocystic, with no internal echoes and no mass effect on the surrounding fat. The classic signature of HA.

Four parts

PART 1

Filler on imaging

Hyaluronic acid, calcium hydroxylapatite, PLLA, PMMA, silicone, polyacrylamide gel and fat on ultrasound, MRI, CT and PET, and the incidental-finding traps each one sets.

PART 2

Doppler in vascular events

Finding the occluded vessel, reading flow and perforator patterns, guiding hyaluronidase to the deposit, and knowing when the scan says to keep going or stop.

PART 3

Nodules and late reactions

Accumulation, biofilm, hypersensitivity, granuloma or abscess: what the image shows, what to give first, and how to measure response on follow-up scans.

PART 4

Ordering imaging and reading the report

Which study for which question, what to write on the request, what a useful report contains, and how radiologists should describe filler.

Who it is for

Injectors with a probe

You own a handheld ultrasound or took a hands-on day and want to read what you see with confidence.

Medical directors and practice owners

You sign the protocols, order the imaging and carry the outcome when something goes wrong.

Radiologists and sonographers

Aesthetic practices are sending you filler patients and you want a clear standard for what to look for and report.

Your instructor

Thomas McCann, MD is a board-certified diagnostic radiologist with fellowship training in musculoskeletal imaging at Yale and mini fellowships in body, breast and neuro imaging. He reads outpatient imaging full time and has been named an NJ Top Doc in radiology four years running.

He is also the founder, medical director and sole injector at Artemis Modern Aesthetics, a physician-only practice in Medford, New Jersey, where he performs every injectable, laser and device treatment himself. The course comes from both rooms at once: the images, the decisions and the documentation that hold up when a complication happens.

Short episodes on filler, imaging and complications, hosted by Dr. McCann with co-host Alexandra. A good way to see how he teaches before the course opens.

Questions

Is there CE or CME credit?
Not at launch. Accreditation is planned if there is enough demand.
Do I need an ultrasound device?
No. Parts 1, 3 and 4 are useful without one. Part 2 is most useful if you scan.
Is this a hands-on course?
No. It is an online course about reading and acting on images. It pairs well with a hands-on scanning day.
What is in the Protocol Pack?
Editable Word protocols written by Dr. McCann for vascular occlusion, hyaluronidase dosing, ultrasound triage, the emergency kit, ophthalmology and radiology referral, and event documentation, for your medical director to adapt.
