Cervical spine trauma, particularly at the craniocervical junction, can produce significant morbidity and mortality in the pediatric population. Although normative pediatric cervical spine CT measurements have been reported, the accuracy of these measurements for predicting ligamentous injury remains unknown. The purpose of this study is to evaluate the sensitivity and specificity of normative pediatric CT measurements for prediction of traumatic ligamentous injury at the craniocervical junction, using MRI as gold standard.

The purpose of this exhibit is to review imagings findings of anomalous pulmonary venous return on angiotomography and describe anomalies associated.

Magnetic resonance (MR) imaging and computed tomography (CT) are used in diagnostic and follow – up the congenital vein anomalies. CT provides superior spatial resolution and short time but there is exposure to ionizing radiation. However in many hospital there are only the possibility of obtain CT imaging in neonates and infant.
The total anomalous pulmonary venous return (TAPVR) is the result of failure of the common pulmonary vein to connect to the left atrium with persistence of the primitive splanchnic connections of the pulmonary veins. There are four categories: supracardiac, cardiac, infracardiac and mixed.
The partial anomalous pulmonary venous return (PAPVR) occurs when some but not all segments of the developing lung failed to establish connections with the common pulmonary vein.

The structure of the heart is more complex than 4 major chambers, 4 major valves, venous inflow and arterial outflow.

Muscular and soft tissue ridges, perforated membranes, tissue flaps, electrical pathways, external grooves, endocardial surface characteristics, and a core architecture structured of fibrous tissue and embryonic tissue remnants form distinguishing anatomic landmarks. These structures provide insight into cardiac development, serve physiologic purpose, define structural and functional elements, as well as offer prognostic information.

Specific details of cardiac anatomy may not be recognized on cardiac MR and CT examinations. Structural anomalies that affect cardiac function and anatomic or physiologic relationships may be abnormal in hearts with congenital malformations. The fine structural details of the heart are typically not part of an imagers search pattern and are therefore overlooked or underreported. Each minute structure and anatomic characteristic provides clues to errors in cardiac formation and may provide clinically relevant diagnostic information. After palliation of CHD defining anatomic structure may be lost, displaced, interrupted or even restored.

Important processes, corresponding anatomic landmarks, and effects of malformation in defining congenital heart disease anatomy, physiology and functional variation from normal include basal structures such as the central fibrous body of the heart, atrial structures including the crista terminalis, the sinus venarum, and eustacian valve, and ventricular structures such as the crista supraventricularis.

Each structure is described along with its normal location, anatomy functional and physiologic importance, the effect of congenital malformation, and imaging findings as in the example of the central fibrous body (table 1).

Minute cardiac anatomy will be shown in illustration as well as in CT and MR images (figure 1).

Pediatric head CT examinations remain a mainstay imaging modality, frequently utilized to evaluate a wide spectrum of pediatric pathology. Current pediatric head CT protocols aim to use the least amount of radiation while providing imaging of diagnostic quality. Lower radiation doses, along with other factors, can occasionally cause CT artifacts that can affect the quality and the interpretation of images.
In this exhibit, we review examples of physics-based, patient-based and scanner-based CT artifacts on head CT exams, while also providing a brief explanation of the underlying physics and ways to mitigate the artifact. Imaging examples include among others: apparent posterior fossa masses due to beam hardening, apparent extra-axial fluid collections due to cupping artifact, apparent brain parenchymal hypodensities concerning for infarct, and apparent beading of intracranial vessels due to lower radiation doses administered.
Awareness of these artifacts is critical for radiologists, as they can potentially lead to misdiagnosis.

Global mAs reduction is accepted as being superior to bismuth breast shields in reducing breast organ dose for children undergoing CT of the chest. However, in imaging of chest, abdomen, and pelvis (CAP), globally reducing mAs degrades image quality in the abdomen and pelvis. This study compares bismuth shields to global mAs reduction including a region-specific boost feature to maintain abdominal image quality. Read More

Accidents remain a top cause of morbidity and mortality in pediatric patient. Assessment for blunt trauma to the abdomen is difficult in the trauma patient and findings of bowel injury can be subtly or confounded by visceral injuries. The most specific finding of free air in blunt hollow visceral organ is often minimally present, or entirely unseen. The pediatric radiologist must be familiarity with the more often seen and less specific secondary signs on CT, including free fluid, bowel wall thickening, and mesenteric contusion injury. We present, by case example, bowel injuries in the traumatic pediatric patient and their management and outcomes, while addressing common pearls and pitfalls. As many of these patients do well with non-operative treatment the radiologist must also be familiar with findings that would allow such option, to appropriately advice referring providers and manage potential re-image of the pediatric patient.

The female anatomic equivalent of the male processus vaginalis is the canal of Nuck. The canal is formed from a small peritoneal protuberance from the round ligament that extends through the inguinal ring, into the inguinal canal, and terminates in the labia majora. Obliteration of the canal occurs in a superior to inferior direction and usually completes within the first year of life. Non-closure results in a persistent canal of Nuck. Very rarely herniation of abdominal and pelvic contents into the canal of Nuck can occur, much less commonly in females than in the male equivalent. Hernias can present at any age but are most common in children. Recognition of this entity is especially important in cases of ovarian herniation due to the risk of incarceration.
We will provide a review normal anatomy, potential canal contents, the imaging appearance on ultrasound, CT, as well as MRI, and discuss differential diagnosis using cases of canal of Nuck hernia in 4 patients aged 22 days though 17 years.

Although Tuberculosis (TB) is very common in early childhood, we see an increased incidence of TB in adolescents due to increased susceptibility. It is also important to note that adolescent TB affects those living in low/middle income countries where TB is very common. There is a paucity of literature regarding the sequelae of TB disease in adolescents based on advanced cross-sectional imaging. We aimed to review the imaging features seen on CT imaging of the chest post adolescent TB in a cohort of patients from Peru. Read More

Computed tomography with its excellent spatial and temporal resolution remains valuable diagnostic modality in pediatrics. On the other hand there has been increasing attention placed on the radiation risks associated with CT imaging, especially in children.
In recent years many advances in CT hardware and software, for example automatic exposure control tools and iterative reconstruction techniques allowed for the reduction of applied radiation dose while maintaining image quality.

The aim of our educational exhibit is:

- to present optimal protocols for chest CT in the youngest age group of children, scanned according to body weight protocols (0-10kg; 10-30kg) with assesement of image quality and dose indices (CTDIvol and DLP; SSDE)
- to present pictorial review of the pediatric chest pathologies in low dose chest CT

Anomalous Aortic Origin of Coronary Artery (AAOCA) is the 2nd most common cause of sudden cardiac death in the young. Coronary artery origins are evaluated as part of transthoracic echocardiography (TTE) and diagnostic precision may be limited by technical limitations, operator dependence, and patient cooperation. MRI and gated Cardiac Computed Tomographic Angiography (CCTA) are often utilized in patients where an anomaly is suspected on TTE. There is limited literature comparing TTE and CCTA in children with suspected AAOCA. The purpose of this study is to determine the distribution of various coronary anomalies comparing TTE and CCTA data, and define the added value advanced imaging brings in clinical decision-making.
