ABSTRACT
AIM: The primary goal of our study was to evaluate the value and accuracy of fine needle aspiration cytology (FNAC) in the diagnosis of various intraoral lesions and to correlate the cytological diagnosis with final histopathological findings. MATERIALS AND METHODS: Fine needle aspiration was performed in 229 patients presented with different lesions of the oral cavity at our institution. Cytological findings were then compared with final histopathological diagnosis. RESULTS: With a male to female ratio of 1.79:1, 229 patients presented with different lesions of the oral cavity were aspirated. Histopathological correlation was available in 86.9% of cases while inadequate material was obtained in 13.1% cases. The diagnostic accuracy of fine needle aspiration in diagnosing benign, pre-malignant and malignant lesions were 95.8%, 84.6% and 97% respectively. Overall the diagnostic accuracy of FNAC in diagnosing intraoral lesions was 94.9% with sensitivity and specificity of 93.2% and 96.8% respectively. CONCLUSION: FNAC of intraoral lesion is recommended as a valuable procedure for the initial evaluation of all intraoral lesions as it is simple, inexpensive, convenient and comfortable to the patient. Moreover, it can offer a rapid and accurate diagnosis for further management of the patient.
ABSTRACT
Liver biopsies are performed for both focal and nonfocal lesions (parenchymal). In our center, majority of liver biopsies are performed for parenchymal liver disease. Parenchymal liver biopsy plays a key role in the diagnosis of various diffuse liver dysfunctions. Results of the biopsy help grade the disease, facilitating prognostication, which helps in planning specific treatment strategies. Imaging guidance is gaining wide acceptance as the standard procedure. Ultrasound (US) guidance is currently considered the most cost-effective and safe way to perform parenchymal liver biopsies. Radiologists worldwide and particularly in the United States are increasingly performing this procedure. Radiologists performing biopsies generally use the cutting needle. Different needle sizes, techniques and preference for biopsy of the right or left lobe have been described. We attribute these preferences to prior training and individual radiologist's comfort level. We describe the algorithm followed at our institution for performing percutaneous US-guided parenchymal liver biopsy. While clinical societies have recommended a minimum of 40 liver biopsies as a requirement for proficiency of clinicians, specific to radiology trainees/fellows interested in pursuing a career in intervention, we feel a total of 20 liver biopsies (includes assisted and independently performed biopsies under supervision) should be adequate training.
