  • Title: [Indications for low-dose CT in the emergency setting].
    Author: Poletti PA, Andereggen E, Rutschmann O, de Perrot T, Caviezel A, Platon A.
    Journal: Rev Med Suisse; 2009 Aug 19; 5(213):1590-4. PubMed ID: 19754008.
    Abstract:
    CT delivers a large dose of radiation, especially in abdominal imaging. Recently, a low-dose abdominal CT protocol (low-dose CT) has been set-up in our institution. "Low-dose CT" is almost equivalent to a single standard abdominal radiograph in term of dose of radiation (about one sixth of those delivered by a standard CT). "Low-dose CT" is now used routinely in our emergency service in two main indications: patients with a suspicion of renal colic and those with right lower quadrant pain. It is obtained without intravenous contrast media. Oral contrast is given to patients with suspicion of appendicitis. "Low-dose CT" is used in the frame of well defined clinical algorithms, and does only replace standard CT when it can reach a comparable diagnostic quality.
