Applications of Thin Needle Aspiration Biopsy in Urology

Journal of Urology, 1979
Percutaneous thin needle aspiration biopsy was done on 34 patients for better staging of malignant disease by study of opacified lymph nodes, on 12 patients to eliminate the possibility of a malignant etiology of ureteral obstruction and on 7 patients with potentially metastatic soft tissue or visceral lesions.

Implementation of a numerical needle method for thin-film design

Applied Optics, 1995
There is a need for different thin film design techniques. Different methods are often required for the solution of different types of problems. A very powerful thin film design procedure, called the needle method, has been developed by Tikhonravov et al.1-8 This method allows new layers to be added to an existing multilayer solution.

Thin spinal or biopsy needle guidance.

Radiology, 1985
The thin needles that are used for myelography or biopsy are easily deflected in the body. We describe a simple method used to guide the tip of these needles to the target area using needle-hub rotation. This procedure was successfully used in more than 260 direct C1-C2 punctures for cervical myelography.

Boundary Layer over a Thin Needle

The Physics of Fluids, 1967
An equation governing the motion of an incompressible fluid flowing axially over a thin paraboloid of revolution is derived. The asymptotic behaviors and an approximate solution are discussed, and numerical solutions computed. From the numerical solutions, an extrapolation towards vanishing boundary thickness is made. It is found that for progressively

Thoracic biopsy: CT guidance of thin-needle aspiration

American Journal of Roentgenology, 1984
CT-guided percutaneous thin-needle aspiration biopsy of 23 mediastinal and 27 other thoracic masses was performed in 40 patients over a 2-year period. Although biplane fluoroscopy is considered the optimal guidance mechanism for thoracic biopsy, CT was required in this group of patients to ensure accurate needle placement within the lesions or within ...

Cervicofacial Actinomycosis: Rapid Diagnosis by Thin-Needle Aspiration

Archives of Otolaryngology - Head and Neck Surgery, 1978
Thin-needle aspiration cytology is a well-known minimally invasive technique that is used in the diagnosis of neoplastic disease. The same biopsy technique provides a means for immediate identification of actinomycosis. Aspiration specimens may be used for morphologic studies, as well as for microbiologic isolation. The diagnostic histologic feature of

Rapid Diagnosis of Actinomycosis by Thin-needle Aspiration Biopsy

American Journal of Clinical Pathology, 1978
Actinomycosis was diagnosed in three cases by the use of thin-needle aspiration biopsy technic. Aspiration was utilized for morphologic studies and collection of material for microbiologic isolation. The critical histologic features of sulfur granules remain intact with aspiration technic.

THIN-NEEDLE BIOPSY OF THE THYROID GLAND IN THE DIAGNOSIS OF THYROTOXICOSIS

Acta Endocrinologica, 1962
ABSTRACT Thin-needle biopsy was carried out in 19 patients with toxic and in 17 patients with non-toxic goitres. The diametres of the cell nuclei of 100 thyroidal epithelial cells in each smear were measured with an ocular micrometer. The nuclear diameter was graded in three groups according to size, i.e.

Cystic lymphangiomas: CT diagnosis and thin needle aspiration

The British Journal of Radiology, 1984
Cystic lymphangiomas of the retroperitoneum are rare benign tumours (Castellino & Finkelstein, 1975) which have previously been difficult to diagnose by conventional radiographic techniques (Hamilton & McInerney, 1981). These tumours have been evaluated by several modalities: computed tomography, ultrasound, thin needle aspiration, and lymphangiography

Peritonitis after thin-needle aspiration biopsy of an abscess

American Journal of Roentgenology, 1981
Thin-needle aspiration biopsy is a well established method for cytologic and/or histologic diagnosis of superficial and deep pathologic masses of the chest and abdomen [1-9]. Although several thousands of cases have been reported, local complications have been reported only namely [10, 1 1 1. We document a case of peritonitis after aspiration biopsy of
