Core Tip
Core Tip: This retrospective study evaluates the application of streak metal artifact reduction technique (SMART) in cone-beam computed tomography (CBCT)-guided percutaneous transthoracic needle biopsy. SMART iterative reconstruction, particularly in full volume-of-interest mode, significantly reduces radial, streak, and dark stripe artifacts caused by metallic coaxial needles compared to original CBCT images. This technology enables clearer visualization of small lung nodules and critical adjacent anatomical structures, such as blood vessels, which is crucial for accurate puncture path planning. The quantitative improvement in image quality confirms the clinical value of SMART in enhancing the precision and safety of biopsies for small pulmonary lesions.
