“…The ‘Black‐bone’ MRI sequence has been used previously in the craniofacial skeleton, to offer a non‐ionizing alternative to CT in children with skull abnormalities 5 ,. 6 , 21–24 Robinson et al 25 . found that foetal ‘Black‐bone’ MRI could be used in the assessment of spinal abnormalities, therefore reducing the risks of ionizing radiation to the mother and the foetus.…”

Background This study will examine the differences between human lumbar vertebrae, three‐dimensional (3D) scans of these bones, 3D models based on ‘Black‐bone’ magnetic resonance imaging (MRI) scans, and 3D‐printed models. Materials and Methods 3D mesh models were created from the “Black‐bone” MRI data from two cadaveric human spines, and then 3D printed. Four models were analysed and compared: anatomic bones, 3D‐scanned models, MRI models and 3D‐printed models. Results There was no significant difference between when comparing the average of all measurements between all model types (p = 0.81). The mean dice coefficient was 0.91 (SD 0.016) and the mean Hausdorff distance was 0.37 mm (SD 0.04 mm) when comparing the MRI model to the 3D‐scanned model. The mean volumes for the MRI model and the 3D scanned model were 10.42 and 10.04 ml (p = 0.085), respectively. Conclusions The ‘Black‐bone’ MRI could be a valid radiation‐free alternative to computed tomography for the 3D printing of lumbar spinal biomodels.

“…Three-dimensional surface images provided by stereophotogrammetric photography allow for full representation of the entire contour of the head without ionizing radiation (Shah et al, 2011; Engel et al, 2012). As an aside, MR protocols, such as Black Bone MRI and GA-VIBE MRI, have been recently published as a new alternative to CT for pre- and postoperative evaluation of head shape (Patel et al, 2020; Saarikko et al, 2020). Three-dimensional photography has been shown to be equivalent to CT scans for anthropometric measurements (Mendonca et al, 2013).…”

“…Three-dimensional stereophotogrammetric photography is susceptible to hair artifacts as the child ages, which is not true with CT scans. Even though the risk of ionizing radiation can be significantly limited using special bone imaging protocols (Stewart et al, 2018), it seems clear that “ALARA” principles (As Low As Reasonably Achievable), as well as new MR protocols being developed, will only continue to favor limiting the use of CT for shape outcomes in studies of craniosynostosis outcomes (Patel et al, 2020; Saarikko et al, 2020).…”

Aim: Metopic craniosynostosis (MCS), with its trigonocephalic head shape, is often treated with either limited incision strip craniectomy (LISC) followed by helmet orthotic treatment, or open cranial vault reconstruction techniques (OCVR). There is controversy regarding resultant shape outcomes among craniofacial surgeons. Those adverse to LISC claim normal head shape is never attained, while proponents believe there is gradual correction to an equivalent outcome. This study aims to quantitate, over time, the three-dimensional (3D) head shapes in patients who have undergone LISC or OCVR intervention for MCS. Methods: Sixty-three 3D images of 26 patients with MCS were analyzed retrospectively. Head shape analyses were performed at: (1) preoperative, (2) 1-month postoperative, (3) 10 to 14 months postoperative (1 year), and (4) 2 years postoperative. Composite 3D head shapes of patients were compared at each time point. Two-dimensional (2D) standardized cross sections of the forehead were also compared. Results: Composite head shapes for both groups were nested, to allow visual comparison as the child’s forehead grows and expands. The difference between LISC and OCVR 2D cross sections was calculated; 108.26 mm preoperatively, 127.18 mm after 1-month postoperative, 51.05 mm after 10 to 14 months postoperative, and 27.03 mm after 2 years postoperative. Conclusions: This study found excellent head shape outcomes for both the LISC and OCVR techniques at 2 years of age. It also corroborates the slow and progressive improvement in head shape with the LISC technique. This study highlights the advantages of 3D photography for measurement of contour outcomes, utilizing both 2D vector and 3D whole head analytical techniques.

“…However, this exposes infants to ionizing radiation which should be avoided [24]. One alternative imaging method is Black Bone magnet resonance imaging [23,54], which has the notable drawbacks that during image acquisition, infants are required to be sedated to prevent them from moving. Sonographic examinations and 3D photogrammetry are radiationfree and broadly available diagnostic options.…”

The assessment of craniofacial deformities requires patient data which is sparsely available. Statistical shape models provide realistic and synthetic data enabling comparisons of existing methods on a common dataset.We build the first publicly available statistical 3D head model of craniosynostosis patients and the first model focusing on infants younger than 1.5 years. For correspondence establishment, we test and evaluate four template morphing approaches. We further present an original, shape-modelbased classification approach for craniosynostosis on photogrammetric surface scans. To the best of our knowledge, our study uses the largest dataset of craniosynostosis patients in a classification study for craniosynostosis and statistical shape modeling to date.We demonstrate that our shape model performs similar to other statistical shape models of the human head. Craniosynostosis-specific pathologies are represented in the first eigenmodes of the model. Regarding the automatic classification of craniosynostis, our classification approach yields an accuracy of 97.3 %, comparable to other state-of-the-art methods using both computed tomography scans and stereophotogrammetry.Our publicly available, craniosynostosis-specific statistical shape model enables the assessment of craniosynostosis on realistic and synthetic data. We further present a state-of-the-art shape-modelbased classification approach for a radiation-free diagnosis of craniosynostosis.
