Ct Guided Biopsy

Diagnosis of thoracic lesions on the basis of history and physical examination is often challenging. Diagnostic imaging is therefore of paramount importance in this field. Radiology has traditionally been considered the diagnostic procedure of choice for these diseases. Nevertheless, it is often not possible to differentiate inflammatory/infectious lesions from neoplastic diseases. A correct cytological and histopathologic diagnosis is therefore needed for an accurate diagnosis and subsequent prognostic and therapeutic approach. In human medicine, Computed Tomography (CT) and CT-guided biopsy are used in the presence of lesions which are not adequately diagnosed with other procedures. In the present study, thoracic lesions from 52 dogs and 10 cats of different sex, breed and size underwent both CT-guided fine-needle aspiration (FNAB) and tissue-core biopsy (TCB). Clinical examination, hematobiochemical analysis and chest radiography were performed on all animals. In this study, 59 of 62 histopathological samples were diagnostic (95.2%). Cytology was diagnostic in 43 of 62 samples (69.4%). General sensitivity, accuracy and PPV for FNAB and TCB were 67.7%, 67.7% and 100% and 96.7%, 95.2% and 98.3%, respectively. Combining the two techniques, the overall mean accuracy for diagnosis was 98.4%. Nineteen of 62 cases showed complications (30.6%). Mild pneumothorax was seen in 16 cases, whereas mild hemorrhage occurred in three cases. No major complications were encountered. CT-guided FNAB cytology can be considered a useful and reliable technique, especially for small lesions or lesions located close to vital organs and therefore dangerous to biopsy in other way.

Abstract Background To investigate the clinical value of CT-guided percutaneous fine-needle aspiration biopsy for peritoneal lesions of unknown nature. Methods A retrospective analysis was conducted of 84 patients with peritoneal thickening for unknown reasons. There were 26 males and 58 females who underwent CT-guided percutaneous fine-needle aspiration biopsy for peritoneal lesions. Result Among these 84 patients, no definite pathologic diagnosis was made in 3 patients, who were lost to the follow-up. The accuracy rate of CT-guided percutaneous fine-needle aspiration biopsy was 95.1% (77/81). Sixty lesions were pathologically-diagnosed with malignancies (74.1%), including 55 with peritoneal metastases, 4 with malignant mesotheliomas, and 1 with a lymphoma. Twenty-four patients (33.8%) were diagnosed as benign lesions, including 11 with tuberculosis and 13 with inflammatory lesions. The complications of CT-guided percutaneous fine-needle aspiration biopsy included bleeding in 1 patient and ascites leakage in 2 patients. Conclusion CT-guided percutaneous fine-needle aspiration biopsy is a safe and effective method for diagnosing peritoneal lesions.

The results of 44 trephine (OD 1.4–4 mm) biopsies and 39 fine needle (0.7–0.9 mm) aspirations of skeletal, mainly vertebral, lesions performed under CT-guidance in 54 patients were evaluated. The fine needle sample was aspirated through the trephine as a complementary procedure in 29 patients and a fine needle aspiration only was performed in 10 patients. Trephine biopsy only was performed in 15 patients. Sufficient material for histologic and cytologic analyses was obtained in 93% (41/44) and 97% (38/39) and a correct benign or malignant diagnosis was obtained in 84% (37/44) and 90% (35/39), respectively. Among the combined examinations the fine needle aspiration alone was diagnostic in 2 cases while the trephine specimen alone provided diagnostic material in 2 cases. In 24 cases both the cytologic and histologic samples were adequate for diagnostic purposes. In one case both methods gave false-negative results. The combined use of cytologic and histologic samples in CT-guided bone biopsies increased diagnostic accuracy. The aorta was perforated once with a 1.4-mm needle but without sequelae. CT-guided bone biopsy was found to be a safe, reliable and cost-efficient method.

INTRODUCTION: The study is an attempt to evaluate the sensitivity, specificity, positive predictive value, negative predictive value, p Value and complications of CT guided thoracic interventions fine needle aspiration cytology and core biopsy which are used for diagnosing benign and malignant thoracic lesions. MATERIAL AND METHODS: Study included 102 Patients (87 males and 15 females) with age group ranged from 15 to 87 years.A total of 143 CT guided interventions (84 FNAC’s and 59 core biopsies) were performed in 102 patients. The tissue obtained was sent to the laboratory for histopathological and cytological analysis for a final diagnosis which would contribute to patient management. RESULTS: All( 59) core biopsies were successful in procuring adequate tissue for histopathological analysis and the yield of core biopsies was 100% .However out of 84 FNAC’s only 4 were unsuccessful in procuring adequate tissue with a failure rate of 4.8%. Post procedural biopsy complications were only three (2.1%) which were small pneumothorax. There were 75 malignant lesions and 23 benign lesions based on cytology and histopathology (4 were excluded due to inadequate sample). There was good agreement between benign and malignant lesions diagnosed on CT and that diagnosed by pathology. The most common benign and malignant lesions were granulomatous lesion and squamous cell carcinoma. CONCLUSION: Percutaneous CT guided interventions like core biopsy and fine needle aspirations cytology are simple minimal invasive procedures with good patient acceptance and low morbidity and almost negligible mortality. CT guided interventions should be performed early for diagnosis of thoracic lesions.
