PURPOSE
We aimed to investigate the effectiveness and complications of transthoracic CT-guided biopsy techniques.METHODS
A total of 94 CT-guided percutaneous transthoracic biopsy procedures performed in 85 patients were retrospectively evaluated. Core biopsy technique was used in 87 procedures and transthoracic fine-needle aspiration biopsy was used in seven procedures.RESULTS
Diagnostic results were achieved in 79 of 94 biopsy procedures. Pathology results were malignant in 54 patients, suspicious for malignancy in three patients, benign in five patients, and benign nonspecific in 17 patients. Specific diagnoses were obtained in 59 patients (62.8%) using core biopsy, but no specific diagnosis could be reached with transthoracic fine-needle aspiration biopsy. Complications included pneumothorax in 27 patients (28.7%) and parenchymal hemorrhage during and after the procedure in eight patients (8.5%).CONCLUSIONS
CT-guided percutaneous transthoracic needle biopsy is a highly accurate procedure for histopathological diagnosis of thoracic masses. In addition, percutaneous transthoracic biopsy has an acceptably low complication rate and it reduces the need for more invasive surgical procedures.Since the beginning of the 21st century, lung cancer has been cited as one of the most common causes of death (1). World Health Organization declared lung cancer as the first leading cause of death in men and second in women, among all types of cancers (2).Percutaneous transthoracic biopsies are performed either using fine-needle aspiration biopsy (transthoracic fine-needle aspiration biopsy, TTFNAB) method or using the incisional or core biopsy method. Incisional biopsy and core biopsy are used to obtain a part of tissue from the lesion for histological diagnosis. On the other hand, TTFNAB is used to obtain aspiration material, which is used for cytological examination and lesion diagnosis (3, 4).Indications of transthoracic needle biopsy include solitary and multiple pulmonary nodules, mass lesions, persistent focal infiltration, consolidation, presence of cavities and abscesses, pleural lesions, and mediastinal and hilar mass diagnosis (3, 5).The aim of this study was to investigate the technique, suitability, and complications in CT-guided transthoracic biopsy of lung masses. 相似文献7.

ObjectiveThe aim was to compare coronary high-definition CT (HDCT) with standard-definition CT (SDCT) angiography as to radiation dose, image quality and accuracy.ResultsThe intraclass correlation coefficient (ICC) of measured vessel attenuation values in SDCT between the two radiologists was exceedingly good. The ICC was higher in HDCT. The radiation dose of HDCT was higher than that of SDCT. The mean tube current was 180 (mA) in HDCT and 147(mA) in SDCT with the same tube voltage (kVp). There was no significant difference between image quality.ConclusionHDCT has a higher radiation dose but has much more atenuation and the spatial resolution which improve measurement accuracy for imaging coronary arteries. 相似文献
