TissueDB/Materials/Olives

Olives — the olive fruit, green or black — are used in medical simulation to represent palpable nodules and masses within tissue phantoms. When embedded in agar or gelatin matrices, olives appear as hyperechoic structures on ultrasound, providing targets for fine needle aspiration training and nodule localisation.

Tissues

Tissue	Visual	Tactile	Simulator	Notes
Thyroid				Pitted green olives embedded in agar create hyperechoic inclusions for thyroid nodule localisation and FNA training.
Breast Lesions				Green olives suspended in a black-ink agar phantom stand in for breast lesions in ultrasound-guided core-needle biopsy training; olive material inside the needle confirms a correct biopsy.^[1] A pimento olive with a radiotracer-injected pea inside it, embedded in a turkey breast, stands in for an occult breast lesion in radio-guided localisation training.^[2]
Lymph node				Small pitted olives simulate lymph node targets at varying depths.
