A new model that would allow interventional radiologists (radiologists who specialize in fine needle aspiration, fine needle biopsy and radiofrequency ablation) to better estimate patient radiation skin doses during CT guided interventional procedures has been developed according to a study performed at the Agios Savvas and Konstantopoulio Hospitals in Athens, Greece.

Core Needle Breast Biopsy Safe for Patients Taking Blood Thinners

Unnecessary biopsies could be a thing of the past for patients undergoing treatment for head and neck cancer. New Saint Louis University research found that when nuclear medicine clinicians and treating physicians work together to interpret PET-CT scan results, the accuracy dramatically improves, sparring patients unnecessary pain and suffering.

Hormone therapy increases frequency of abnormal mammograms, breast biopsies

harminka — Tue, 26 Feb 2008 01:32:39 -0600

Combined hormone therapy appears to increase the risk that women will have abnormal mammograms and breast biopsies and may decrease the effectiveness of both methods for detecting breast cancer, according to a report in the February 25 issue of Archives of Internal Medicine, one of the JAMA/Archives journals.

Patients with complex fibroadenomas can avoid surgery

Complex fibroadenomas have a low incidence of malignancy, so women with this condition can be more conservatively treated and avoid surgical biopsy, according to a new study by a team of researchers from the Hadassah-Hebrew University Medical Center in Jerusalem.

Device Zeroes in on Small Breast Tumors

A new medical imager for detecting and guiding the biopsy of suspicious breast cancer lesions is capable of spotting tumors that are half the size of the smallest ones detected by standard imaging systems, according to a new study.

Virtual biopsy cuts out need for diagnostic surgery

A non-invasive diagnostic tool to detect surface cancers quickly and painlessly using technology currently employed by gyms to calculate body composition has been developed by a QUT PhD medical physics researcher.

Using biopsy-scoring data may help determine prostate cancer prognosis

harminka — Wed, 03 Oct 2007 06:53:43 -0500

Men with certain scores and patterns based on prostate cancer biopsy were found to be at higher risk of PSA-failure, suggesting that this measurement could help predict the risk of prostate cancer recurrence, according to preliminary research published in the October 3 issue of JAMA.

MRI allows detection of more breast cancers in high-risk women

harminka — Tue, 31 Jul 2007 05:27:50 -0500

Magnetic resonance imaging (MRI) enables radiologists to accurately identify tumors missed by mammography and ultrasound, according to a multicenter study comparing the three screening methods in women at high-risk for breast cancer. The findings of the study appear in the August issue of the journal Radiology.

Novel hydrogels for repairing, regenerating human tissue

University of Delaware scientists have invented a novel biomaterial with surprising antibacterial properties that can be injected as a low-viscosity gel into a wound where it rigidifies nearly on contact--opening the door to the possibility of delivering a targeted payload of cells and antibiotics to repair the damaged tissue.

Nanoparticles that cancer cells can't resist

TURNING cancer cells into mini magnets by using nanoparticles could make biopsies so sensitive and efficient that there will be no need to repeat these invasive tests.

Improving diagnostic yield in peripheral lung lesions

The combined use of two minimally invasive techniques—endobronchial ultrasound (EBUS) and electromagnetic navigation bronchoscopy (ENB)-- in the diagnosis of peripheral lung lesions has been shown to be more effective than either procedure alone and does not compromise patients’ safety, according to a new study.
