Document Summary

Protocol: every individual imaging area will have a protocol manual that covers, patient prep, pre procedure blood work requirements, contraindications, procedure set up, image requirements, post procedure requirements. Indications for biopsy: query possible/likely malignancy, obtain tissue for molecular profiling type of cancer, targeted treatment planning, confirmation of met disease, presence of parenchymal disease (hepatitis, transplant rejection, determine nature of atypical or incidentally discovered mass. Pre biopsy considerations: patient prep (npo, iv fluids, contrast, consent, core biopsies: vascular organs ptt, inr, platelet levels, discontinuation of anticoagulants, modality choice will determine prep. Side cutting disposable needles: often found in small clinics, not as stiff, springs are not as strong, not as affective for calcified lesions, used where central equipment processing not available. Contraindications: abnormal clotting or platelet testing, other resources say inr needs to be between 0. 8-1. 2. Inr needs to be < or equal to 1. 5.
