title: [The role of aspiration cytology in tumor diagnostics].
abstract: Fine needle aspiration biopsy (FNAB) of focal lesions is a quick, relatively simple and cost-effective diagnostic method. However, performing aspirations and interpreting smears require skill and experience. Before initiating an aspiration the doctor needs to be aware of the limits of cytology as it is vital to know what kind of diagnostic issues can be answered upon a smear and what kind of questions cannot. Traditionally FNAB was performed without radiologic guidance, and therefore almost only palpable lesions were aspirated. Since ultrasound (US) has become widely used in medicine, it is axiomatical that FNAB is ideally performed with US guidance not only for the protection of the patients but also for targeting the lesion more safely. Several cytologists find US guidance unnecessary as a routinely used examination, which may lead to unsatisfactory smears and false negative results. This means not only a loss for the patient, but leads to a negative judgement of this diagnostic method. Our interventional cytology diagnostic team developed a working method resulting in excellent statistical results. In the followings we would like to share our experience refined the past two decades to restore the reputation of this diagnostic method.
