Precise FNAC can be obtained by using :
Ans. A. USGRef Dahne Radiology Manual 7th/368;Harshmohan 7th/902- l3;Robbins 9th/333Radiological imaging Aids for FNAC:Non-palpable lesion require some form of localization by radiological aids for FNAC to be carried out.Plain X-ray films are usually adequate for lesions within bones & for some lesions within the chestFNAC of chest may also be attempted under image amplified fluoroscopy which allows visualization of needle placement on the television monitorCT guidance is also used for lesions within the chest dy Abdomen.The most versatile radiological aid is ultrasonographic guidance (USG) which allow direct visualization oF needle placement in real time & is free from radiation hazards.It is an extremely valuable aid for FNAC of thyroid nodules, soft tissue masses, intra-abdominal lesions dt for intrathoracic which about the chest wall, but no help in deep intrathoracic lesions or in bony lesionsPrecision of USG and CT scan is comparable for guidance in FNAC from thoracic mass lesions
