A guided broncoscope achieves biopsy of 75 percent pulmonary nodules without puncture or surgery
The release is available in Spanish . A broncoscope guided by means of electromagnetic navigation has managed to achieve the biopsy of 75% of pulmonary nodules greater than 2 cm, according to Doctor Luis Seijo, specialist in Pneumology at the University Hospital of Navarra. This is the hosp...Microcoils help locate small lung nodules
OAK BROOK, Ill. - A new technique combining computed tomography (CT) with fiber-coated surgical microcoils allows physicians to successfully locate and remove small lung nodules without the need for a more invasive procedure, according to a new study published in the February issue of Radiology ....Protein Helps ID Thyroid Cancer Nodules
Test using galectin-3 finds them sooner, could cut unnecessary surgeries MONDAY, May 19 (HealthDay News) -- Testing thyroid nodules for the presence of a lectin molecule called galectin-3 could help improve identification of nodules with cancer and reduce the number of unnecessary sur...PET outperforms CT in characterization of lung nodules
Reston, Va.Researchers involved in a large, multi-institutional study comparing the accuracy of positron emission tomography (PET) and computed tomography (CT) in the characterization of lung nodules found that PET was far more reliable in detecting whether or not a nodule was malignant. CT and ...CAD plus MDCT useful in finding lung nodules
Computer-aided detection combined with MDCT improves radiologists ability to detect solid lung nodules early enough for them to be treated without increasing interpretation time according to a recent study conducted by researchers at Hopital Pitie-Salpetriere in Paris, France.
