Transperianal or transrectal prostate biopsy is necessary to confirm a prostate cancer diagnosis and to grade the tumor specimen. TRUS-guided biopsies of hypoechoic areas may help define extraprostatic extension. For patients with visceral or lytic metastases, these lesions may be biopsied, because this presentation is common for one... 

ALA also appears to have potential for clinical use as a photodiagnostic or photodetection agent. Fluorescence visualized after intravesical instillation of ALA shows some specificity for mucosal lesions including cancer and dysplasias, although false positives caused by inflammatory areas are also seen. However, it is the improvement in sensitivity rather than in specificity that suggests that ALA photodiagnosis could be a useful tool for guiding biopsies.

Guided Biopsy. A biopsy is a time-consuming, sometimes inaccurate, and invasive procedure. Traditionally, doctors obtained a biopsy (sample) of the tissue of interest hy inserting a needle into a patient at the approximate location of the target tissue. However, real-time GT imaging allows doctors to observe the location of the biopsy needle within the patient. Therefore, doctors can obtain a more accurate tissue biopsy in a relatively short time and without using invasive procedures. 

There are also reports describing the use of PCT to evaluate squamous ceU carcinomas of the head and neck. Initial results revealed elevated PS, CBF, and CBV and a lower MTT in the primary tumor site, compared with those values in normal structures (Gandhi et al. 2003 Hayano et al. 2007). PCT may provide a way to measure tumor malignancy noninvasively, guide biopsies to the most malignant portion of the tumor, and as-...
