Biplane fluoroscopy is usually used in angiography. Biplane fluoroscopy gives a biplane image with high resolution during the performance of operations. Trigeminal nerve blocks are effective treatment modalities for trigeminal neuralgia, and maxillary nerve block is the most dangerous procedure among them. The anatomic structures can change after head and neck surgery, so the trigeminal nerve block procedures cannot be done so easily. We used biplane fluoroscopy in these difficult cases. Our first case was a 60-year-old man who had undergone maxillary nerve block. The second case was of a 64-year-old man who had pulsed radiofrequency lesioning of mandibular nerve performed after head and neck surgery. With biplane fluoroscopy, we got good results without any complications.

A 46 years old male showed radiologically a single cavitary nodular lesion in right upper lung, which extended to the regional chest wall. This finding has to be made into differential diagnosis of numerous pulmonary diseases including infections such as mycobacterial, fungal or bacterial, granulomatous diseases, and neoplasms. For the definite diagnosis, fine needle aspiration biopsy guided by biplane fluoroscopy was performed. The aspirates contained several sulfur granules, in the center of which many gram positive, filamentous organisms were compactly intermingled. Such a findings was compatible with pulmonary actinomycosis. Now the lesions is cleared out by medical treatment with amoxicillin for 3 months.

Background : To evaluate how efficaciously and safely we can make transthoracic lung biopsy with an 18-gauge automated biopsy device. Methods : We performed 130 transthoracic needle biopsies including 16 repeat biopsies in 114 patients with a pulmonary mass using an l8-gauge biopsy device (ASAP 18, Microvasive-. Eighty-three biopsies were performed by an experienced radiologist and 47 by several less experienced radiologists. All biopsies were guided by biplane fluoroscopy. Results : We successfully obtained sufficient tissue(>2-mm in the length) in 128(985) of 130 biopsies. Biopsy provided the specific diagnosis in 97 (85%) of 114 patients including 78 (88%) of 89 patients with a malignant tumor and 19 (90%) of 21 patients with a benign condition. The diagnosis could not be made in the remaining four patients. Of interest to note was the superb capability (74/74) of biopsy to make a distinction between small cell carcinoma and non-small cell carcinoma. There was no significant difference in the diagnostic yields between the experienced and less experienced radiologists. Of the total 130 biopsies, pneumothorax appeared in 13 (10%), among which treatment was required in 2 (2%), Mild, self-limiting hemoptysis was nod in seven (5%), but in no case was the treatment required. Conclusion : We conclude transthoracic lung biopsy with an 18-gauge automated device is an effective procedure for the specific diagnosis of benign and malignant lung disease. It is safe with the complication rate comparable to that of fine-needle aspiration biopsy as well.
