Flashcards

T1-weighted Image

A type of ultrasound image where fluid appears dark and fat appears bright.

T2-weighted Image

A type of ultrasound image where both fluid and fat appear bright.

Hyperintense cyst on T1

A type of ultrasound image where the cyst appears bright.

Pelvic Adenomyosis (IOC)

A condition where endometrial tissue grows outside the uterus, often in the pelvic area. This is not a confirmed diagnosis, but rather an impression based on imaging.

Study Notes

Anechoic Cyst

Characterized by an absence of echoes
Shows posterior acoustic enhancement on ultrasound imaging

Reticular/Lacy/Fish Net Appearance

Ultrasound appearance described as reticular, lacy, or fishnet-like

Ground Glass Appearance

Ultrasound appearance described as ground glass

Fluid and Fat Signal Intensity

Fluid: Dark on T1-weighted images
Fat: White on T1-weighted images
T2: White on T2-weighted images

T1 Hyperintense Cyst

Shows high signal intensity on T1-weighted images
Presents with a dot-and-dash pattern on ultrasound

Pelvic Adenomyosis

Diagnosed as Pelvic Adenomyosis with the abbreviation IOC (Impression of)
Presents with a keyhole sign on antenatal ultrasound
