“…Previous literature states that additional CT imaging can reduce the negative appendectomy rate during pregnancy [11,16]. However, ionizing radiation is a significant disadvantage of CT because it is a potential hazard to the developing fetus [11,17]. When the exposure to radiation during a CT scan is less than 500 mGy, no increase in adverse pregnancy outcomes is seen, but the risk for childhood cancer is estimated to increase by 0.1% following a fetal radiation dose of 100 mGy [17].…”

Therefore, given the potential teratogenic and carcinogenic effects of ionizing radiation on the developing fetus, diagnostic medical imaging should be avoided where possible in a pregnant patient and used only when absolutely necessary [10,11].…”

Both (perforated) appendicitis and negative appendectomy during pregnancy are associated with a high risk of premature delivery. Clinical presentation and imaging remains vital in deciding whether surgical intervention is indicated. We recommend to cautiously weigh the risks of delay until correct diagnosis with associated increased risk of appendiceal perforation and the risk of unnecessary surgical intervention. Based upon current literature, we recommend clinicians to consider an MRI following an inconclusive or negative abdominal ultrasound aiming to improve diagnostic accuracy to reduce the rate of negative appendectomies. Accurate and prompt diagnosis of acute appendicitis should be strived for to avoid unnecessary exploration and to aim for timely surgical intervention in pregnant women suspected of having appendicitis.

“…115 Pulmonary CTA and perfusion scintigraphy are both the recommended imaging procedures of choice of the Fleischner Society and the Task Force for the Diagnosis and Management of Acute Pulmonary Embolism of the European Society of Cardiology. [120][121][122][123] One study reported similar radiation doses to the fetus on using 16-slice pulmonary CTA, V/Q scintigraphy, or perfusion scintigraphy alone. 119 There is no clear evidence supporting the superiority of either pulmonary CTA or perfusion scintigraphy as the preferred choice in pregnant women.…”

Pulmonary embolism (PE) is a common disease causing significant morbidity and mortality and results in substantial socioeconomic costs to health care systems worldwide. The correct diagnosis, however, poses many challenges. As a result, ongoing research continues to develop and refine new and existing diagnostic algorithms. In this article, we systematically compare and evaluate the available evidence and cost-effectiveness of diagnostic imaging approaches for patients with suspected PE using data in PubMed and EMBASE up to February 2012. The obtained data were systemically analyzed and presented on the basis of the obtained evidence. A cost-effectiveness analysis of imaging techniques or algorithms has been summarized, if available, in dedicated paragraphs for the major issues on diagnostic imaging of PE that are discussed in this article.

“…International Commission on Radiological Protection guidelines state that fetalradiation doses less than 100mGy should not be a reason for terminating the pregnancy[27]. A recent publication estimated fetal radiation doses from abdominal-pelvic CT between 8.6 and 23.4mGy/100mAs, depending on scanner, kVp, and beam collimation[28]. This is a range in which there is real concern for effects on the fetus.…”

The increase in radiation exposure due to CT scans has been of growing concern in recent years. CT scanners differ in their capabilities and various indications require unique protocols, but there remains room for standardization and optimization. In this paper we summarize approaches to reduce dose, as discussed in lectures comprising the first session of the 2013 UCSF Virtual Symposium on Radiation Safety in Computed Tomography. The experience of scanning at low dose in different body regions, for both diagnostic and interventional CT procedures, is addressed. An essential primary step is justifying the medical need for each scan. General guiding principles for reducing dose include tailoring a scan to a patient, minimizing scan length, use of tube current modulation and minimizing tube current, minimizing-tube potential, iterative reconstruction, and periodic review of CT studies. Organized efforts for standardization have been spearheaded by professional societies such as the American Association of Physicists in Medicine. Finally, all team members should demonstrate an awareness of the importance of minimizing dose.
