Summary of multi-imaging techniques in SCAD adapted from [38].

	Coronarography	IVUS	OCT	CCTA
Advantages	Easily executable Images suggestive of SCAD in most cases	Visualization of the intramural hematoma and the flap	Visualization of the vessel wall, the intimate, the false light, intramural hematoma, and any flaps and areas of communication between the true and false lumen	No possibility of iatrogenic damage Image of the presence of contrast in the false lumen Visualization of intramural hematoma
Limitations	Invasive Image of the vase light but not the wall	Passage of the guide in the coronary artery No identification of the middle intimal membrane No identification of small areas of connection between false and true lumen	Passage of catheter in coronary artery and injection of contrast at high pressure, with the danger of expansion of the dissection itself	Limited data on its use in acute Absence of specific diagnostic criteria for EXP Frequency-dependent motion artifacts Limited utility for pots < 2.5 mm in diameter Difficulty in distinguishing between non calcified atherosclerotic plaques and intramural hematoma
Use	Diagnosis of SCAD	Confirmation of diagnosis	The gold standard method for the confirmation of SCAD	Follow up

IVUS: intravascular ultrasound; OCT: optical coherence tomography; CCTA: coronary computer tomography angiography; SCAD: spontaneous coronary artery dissection.
