1). To obtain the tissue sample of the tumor, percutaneous CT-guided biopsy was arranged. After we review the anatomic location of the mediastinal tumor, trans-sternal needle biopsy was the only way to obtain the tissue sample of the tumor. The para-sternal route was blocked by bilateral internal mammary arteries (Fig. 1).
A retrospective review of 34 patients who underwent CT-guided sternal biopsy was carried out at a single institution. Pre-biopsy CT density, location, penetration length of biopsy needle, number of biopsy attempts, angle of needle approach, final diagnosis, and operator experience level were recorded. A biopsy was
Wherever possible, we prefer to perform needle biopsies under ultrasound guidance, as it is fast, inexpensive, does not use ionizing radiation and provides us with real-time imaging of the position of the biopsy needle relative to the target. However, in many cases ultrasound-guided biopsy is not feasible and CT is required.

PURPOSE: To report our experience with computed tomography (CT)-guided coaxial needle biopsy of intrathoracic lesions by using the transsternal approach. MATERIALS AND METHODS: Medical records of 37 consecutive patients who underwent CT-guided transsternal biopsy of intrathoracic lesions were evaluated.

Conclusion: CT-guided percutaneous sternal biopsy has a relatively lower diagnostic yield. However, acute angle of needle approach may help increase biopsy success rate. Osteoblastic lesions and lesions in the manubriosternal joint tend to have lower diagnostic yield. Keywords. Sternum, computed tomography (CT),
Indications. Percutaneous needle biopsy of the lung is indicated for indeterminate pulmonary nod- ules or masses, particularly those that will likely require chemotherapy or radiation rath- er than surgery, and in patients with a history of extrapulmonary malignancy. Because tar- geted therapy has now become an important.
Different techniques performed with CT and US guidance have been advocated for percutaneous needle biopsy of mediastinal lesions (4–13). .. An inadequate acoustic window and poor lesion visualization can be problems when a US-guided parasternal approach is used for mediastinal biopsy; thus, the use of this
