Purpose : To compare the efficacy of a 20-gauge and an 18-gauge needle in sono-guided percutaneous automated gun biopsy for establishing the specific diagnosis of renal parenchymal disease in pediatric kidneys. Materials and Methods : In 60 pediatric patients with renal parenchymal diseases, percutaneous sono-guided gun biopsy was performed by an experienced radiologist. In two groups of 30 pat...

BACKGROUND Preoperative diagnosis of breast cancer is a standard of care. We conducted a population-based study to determine the factors associated with the use of percutaneous needle biopsy to diagnose breast cancer in Ontario. METHODS We identified a total of 3644 women who underwent breast tissue sampling (percutaneous needle biopsy or surgical excision) that yielded a diagnosis of cancer ...

BACKGROUND The purpose of this retrospective study was to compare the results and complication rate in CT guided percutaneous trans-thoracic fine needle aspiration biopsies (FNAB) and core biopsies of lung lesions, and to determine the applicability of these needles. PATIENTS AND METHODS In 242 patients (166 males; 76 females) with mean age of 58.9 years (13-84 years) CT guided biopsies of lu...

Percutaneous transthoracic core needle biopsy has been advocated as a highly accurate technique for the diagnosis of anterior mediastinal masses. A patient is described with a large anterior mediastinal mass in whom the diagnosis of mediastinal carcinoid tumour was made by transthoracic core needle biopsy. At definitive surgical resection the tumour proved to be a B cell lymphoma. This case ill...

There are various techniques available for percutaneous biopsy of suspected diskitis/osteomyelitis. Our technique has evolved as our experience with percutaneous vertebroplasty has grown. By using a transpedicular approach, we angle a bone biopsy needle in an exaggerated caudocranial trajectory to allow eventual access across the disk space above. This approach permits sampling of the disk spac...

A sheathed needle (Tru-Cut) was compared with a suction biopsy needle (Menghini) in a randomised prospective trial over 18 months to determine whether the former offered any special advantages in routine percutaneous liver biopsy. Seventy-seven consecutive biopsies were performed by a single operator. Although biopsy fragmentation was commoner with the suction needle, the length and volume of t...

thymoma is a term that should be restricted to neoplasms of thymic epithelial cells, irrespective of the presence or the number of lymphocytes. the usual location of thymoma is the antrosuperior mediastinum; however, this tumor can also occur in other mediastinal compartments, in the neck, within the thyroid gland, in the pericardial cavity, the pulmonary hilum, within the lung parenchyma, or t...

Diagnostic and therapeutic image-guided percutaneous interventions have become increasingly important in the clinical management of various conditions. Though precise needle placement via a safe route is essential for successful percutaneous interventions, it is often difficult in cases of deeply situated, small lesions. The present paper describes the efficacy of the directable needle guide (D...

Imaging-guided percutaneous chest biopsy is a commonly performed procedure and considered the minimally invasive gold standard for histopathological investigation of thoracic masses. Recognized complications include pneumothorax, air embolism, and seeding of the biopsy tract. We describe a novel approach to diagnostic sampling of a mediastinal mass in a critically unwell patient using a transju...

PURPOSE To assess feasibility, results and complications in image-guided biopsies using a single needle design in various organs. MATERIALS AND METHODS 100 consecutive percutaneous biopsies were performed in 54 females and 46 males aged 24-87 years (mean age/standard deviation: 64.5 +/- 12 years) using a full-core end-cut tri-axial full-automatic biopsy needle (18 gauge BioPince, InterV-MDTec...
