Cleerly / AI-Analyzed CT Coronary Angiography
Cleerly is an AI-powered analysis platform applied to coronary CT angiography (CCTA), the contrast-enhanced cardiac CT that visualizes both calcified and non-calcified plaque in the coronary arteries. Where coronary artery calcium (CAC) scoring…
Coronary Artery Calcium (CAC) Scoring
Coronary artery calcium scoring is a non-contrast CT scan of the heart that quantifies calcified atherosclerotic plaque in the coronary arteries. The Agatston score, derived from the area and density of calcified deposits, has been the standard…
DEXA Scan — Bone Density and Body Composition
Dual-energy X-ray absorptiometry (DEXA, sometimes written DXA) is the gold-standard imaging modality for measuring bone mineral density and the most accurate consumer-accessible method for measuring body composition (fat mass, lean mass, visceral…
Full-Body MRI (Prenuvo, Ezra, Q Bio)
Full-body magnetic resonance imaging — sold under brands including Prenuvo, Ezra, and Q Bio — is a consumer-direct whole-body MRI scan marketed for early detection of cancer and incidental findings. The scans take approximately 45–60 minutes,…
Polysomnography vs Home Sleep Apnea Testing
Sleep-disordered breathing — primarily obstructive sleep apnea (OSA) — is one of the most common, most underdiagnosed, and most consequential conditions in adult medicine. Untreated moderate-to-severe OSA is associated with hypertension, atrial…

Exosomes for Skin and Hair
Exosomes are nanoscale (30-150 nm) extracellular vesicles released by virtually all cell types as a normal mechanism of intercellular signaling. They carry a defined cargo of proteins, lipids, mRNA, and microRNAs that reflects the parent cell's…
Polylactic Acid (Sculptra) Biostimulator
Sculptra (poly-L-lactic acid, PLLA) is an injectable biostimulator developed by Sanofi-Aventis (now Galderma). Unlike hyaluronic acid (HA) fillers, which physically occupy volume at injection sites, Sculptra works by triggering a controlled…
Polynucleotides (Rejuran and Analogs)
Polynucleotides (PN) are short fragments of DNA, typically extracted from the gonadal tissue of Pacific salmon, processed to produce a defined molecular-weight range of nucleotide chains. The most-recognized branded product is Rejuran…
