Radiation Reduction Strategies in Pediatric Orthopaedics.

Jeffrey R Sawyer

J Pediatr Orthop 2021 Jul;41(Suppl 1):S75-S79

Department of Orthopaedic Surgery, University of Tennessee/Campbell Clinic, Memphis, TN.

Introduction: Pediatric orthopaedic patients have the potential for significant radiation exposure from the use of imaging studies, such as computed tomography and bone scintigraphy. With the potential for long-term treatment, such as is required for scoliosis or osteogenesis imperfecta, patients are at even greater risk of radiation-induced carcinogenesis.

Discussion: Although an association between radiation and cancer risk is evident, causation is difficult to prove because comorbidities or genetic predispositions may play a role in the higher baseline rates of malignancy later in life. Read More

Three-dimensional versus two-dimensional postmortem ultrasound: feasibility in perinatal death investigation.

Pediatr Radiol 2021 Jun 5;51(7):1259-1266. Epub 2021 Mar 5.

Department of Clinical Radiology, Great Ormond Street Hospital for Children, London, WC1N 3JH, UK.

Three- and four-dimensional US techniques in antenatal screening are commonplace, but they are not routinely used for perinatal postmortem US. In this technical innovation, we performed both two-dimensional (2-D) and three-dimensional (3-D) postmortem US on 11 foetuses (mean gestation: 23 weeks; range: 15-32 weeks) to determine whether there was any benefit in 3-D over conventional 2-D methods. In one case of osteogenesis imperfecta, both 2-D and 3-D US images were non-diagnostic because of small foetal size. Read More
