003330. La tomografia computerizzata, in radiologia, indicata con l' acronimo TC o CT (dall' inglese computed tomography ), è una tecnica di indagine radiodiagnostica ( diagnostica per immagini ), con la quale è possibile riprodurre immagini in sezione ( tomografia) e tridimensionali dell'anatomia, create da un'analisi generata al computer ...
OPS-301 code. 3-75. Positron emission tomography–computed tomography (better known as PET-CT or PET/CT) is a nuclear medicine technique which combines, in a single gantry, a positron emission tomography (PET) scanner and an x-ray computed tomography (CT) scanner, to acquire sequential images from both devices in the same session, which are ...
Technique Low-dose high-resolution (1.25 mm) chest CT. HRCT is performed using a conventional CT scanner. However, imaging parameters are chosen so as to maximize spatial resolution: a narrow slice width is used (usually 1–2 mm), a high spatial resolution image reconstruction algorithm is used, field of view is minimized, so as to minimize the size of each pixel, and other scan factors (e.g ...
Contrast CT. A woman undergoing CT pulmonary angiogram, a contrast CT scan of the pulmonary arteries, because of suspected pulmonary embolism. A contrast delivery system is connected to a peripheral venous catheter in her left arm. A CT pulmonary angiogram, in this case showing pulmonary embolism of saddle-type, which becomes more radiolucent ...
Pencitraan resonansi magnetik ( bahasa Inggris: magnetic resonance imaging, MRI) ialah gambaran pencitraan bagian badan yang diambil dengan menggunakan daya magnet yang kuat mengelilingi anggota badan tersebut. Berbeda dengan "CT scan", MRI tidak menggunakan radiasi Sinar-X dan cocok untuk mendeteksi Jaringan Lunak, misalnya Kista ataupun Tumor ...
Collimator used to collimate gamma rays (red arrows) in a gamma camera. Single-photon emission computed tomography ( SPECT, or less commonly, SPET) is a nuclear medicine tomographic imaging technique using gamma rays. [1] It is very similar to conventional nuclear medicine planar imaging using a gamma camera (that is, scintigraphy ), [2] but is ...
Imbasan (atau Skan) tomografi berkomputer ( bahasa Inggeris: computerized tomography atau CT scan) menggabungkan ukuran sinar-X yang diambil dari pelbagai sudut yang berbeza untuk diproses komputer lalu menghasilkan imej ("kepingan" maya) keratan rentas (tomografi, daripada istilah bahasa Yunani gabungan tome "kepingan" dan grafein "menulis ...
