In this article, we briefly review the concept of brain mapping in stereotactic surgery taking into account recent advances in stereotactic imaging. The gold standard continues to rely on probabilistic and indirect targeting, relative to a stereotactic reference, i.e., mostly the anterior (AC) and the posterior (PC) commissures. The theoretical position of a target defined on an atlas is transp...

PURPOSE To determine the cost savings of stereotactic core needle biopsy over open surgical biopsy in patient subgroups defined according to mammographic findings. MATERIALS AND METHODS From July 1992 through February 1995, stereotactic core needle biopsy was performed in 356 women with 405 nonpalpable breast lesions (254 were masses and 151 were calcification). Lesions were classified accord...

Introduction Stereotactic mesencephalotomy is an ablative procedure which lesions the pain pathways (spinothalamic and trigeminothalamic tracts) at the midbrain level to treat medically refractory, nociceptive, contralateral pain. Sparsely reported in contemporary English language literature, this operation is at risk of being lost from the modern-day neurosurgical practice. Methods We present ...

Objective: To evaluate the accuracy of stereotactic coal injection and wire localisation followed by excisional biopsy for occult breast lesions. Experimental design: Prospective study Setting: University Hospital Patients: Forty-five patients with abnormal mammographic findings out of 6543 women undergoing screening mammography. Patients with palpable or ultrasonographically detectable lesions...

Accelerated partial breast irradiation has caused higher than expected rates of poor cosmesis. At our institution, a novel breast stereotactic radiotherapy device has demonstrated dosimetric distributions similar to those in brachytherapy. This study analyzed comparative dose distributions achieved with the device and intensity-modulated radiation therapy accelerated partial breast irradiation....

Treatment of recurrent glioblastoma is still challenging. Stereotactic radiosurgery has been accepted as a treatment option for recurrent glioblastoma after standard chemotherapy and irradiation. However, the efficacy of stereotactic radiosurgery at recurrence has been limited, mainly due to the highly infiltrative nature of the tumor which makes the lesion difficult to define as the target. To...

Infiltrative cerebral gliomas remain a neurosurgical challenge despite the latest achievements in neuroimaging techniques and microsurgical approaches. In this paper the authors present their experience in 85 cases of stereotactic biopsies performed for infiltrative, multicentric and deep-seated cerebral gliomas. The stereotactic and neuroimagistic tools used for these procedures included the L...

BACKGROUND The purpose of this study was to determine the yield of stereotactic core breast biopsy and its cost-saving potential. METHODS This observational study was conducted at the Department of Radiology at Aga Khan Hospital in Karachi. All female patients (n = 84) undergoing stereotactic core breast biopsy under mammographic guidance from January 2005 to May 2010 were included. Stereotac...

S tereotactic pertains to a precise positioning in space. Stereotactic radiotherapy is a successful noninvasive modality for treating intracranial malignancies. Stereotactic radiosurgery was developed as a noninvasive tool to allow access to areas of the head that were previously treated by traditional surgical methods with a high rate of morbidity. As radiotherapy was refined, different stereo...

The distinct radiographic features of psoriatic arthritis (PsA) help confirm it as a distinct entity from rheumatoid arthritis and highlight some unique non-synovial based disease imaging features. The advent of magnetic resonance imaging and a better understanding of joint microanatomy including the complexity of joint entheses provide a unifying anatomical and biomechanical concept that links...
