Patients undergoing lung and stem cell transplants require serial CT examinations and hence dose reduction techniques are mandatory. The newest 3^rd generation dual-source CT scanner incorporates spectral beam shaping at 100 kilovoltage (kVp) using a dedicated tin filter (100 kVp Sn), which improves dose efficiency by removing low-energy photons that contribute little to noncontrast image quality. The purpose of this study was to compare radiation exposure in non-contrast-enhanced pediatric chest CT at 100 kVp Sn imaging and at conventional low kVp imaging in the same patient cohort.

The American College of Radiology (ACR) Dose Index Registry (DIR) compares site or practice exposure indices among regional and national values. While the CT DIR was established in 2011, Digital Radiography (DR) is only in the pilot phase. This single-site, single-vendor experience will inform the pediatric radiology community of the establishment of the ACR DIR DR module. Read More

Scanner console-provided volume CT Dose Index (CTDIvol) and Dose Length Product (DLP) are frequently added up inappropriately to obtain cumulative dose values in patients exposed to multiple multi-sequence CT exams, performed with varying z-axis coverage and often with longitudinal tube current modulation. We present the patient-size specific Dose Line Integral (DLI) as a new metric that allows this task to be performed in a more precise fashion across multiple scanner platforms Read More

Contrast-enhanced ultrasound (CEUS) and shear wave elastography (SWE) have been widely studied in adult thyroid disease. However, evaluation of thyroid nodules using these tools in pediatric patients has yet to be published.
We aim to evaluate the feasibility and safety of CEUS and SWE for thyroid nodules in children at the time of cytologic biopsy. Read More

The renal artery ostial anatomy, balloon profile, and stent deployment are all challenges of complex procedural RAS planning in children. In such cases there is an increased risk of renal artery rupture secondary to angioplasty requiring placement of a covered stent. This study aims to establish the feasibility of simulating renovascular stent deployment in three 3D printed pediatric patient-specific RAS endovascular phantoms. Read More

Conventional Doppler US is known to have low sensitivity for the diagnosis of renal artery stenosis (RAS), in particular segmental renovascular disease. This study aims to determine if contrast-enhanced US (CEUS) can quantitatively provide assessment of renal arterial and parenchymal perfusion pre- and post- renal artery angioplasty in children and potentially be used as a follow-up imaging tool.

Renal artery stenosis (RAS) is an important cause of hypertension in children. When suspected, imaging options include Doppler US, CTA and MRA. However, conventional angiography remains the gold standard. We investigate the accuracy and inter-reader reliability of CTA in children with suspected renal artery stenosis. Read More

Cancer predisposition syndromes (CPS) are rare genetic disorders with increased risk of benign and malignant neoplasms. A few of these syndromes predispose to thyroid gland pathology, including thyroid carcinoma. The purpose of this study is to review the spectrum of diagnostic outcomes of thyroid abnormalities in pediatric patients diagnosed with a CPS at a tertiary care pediatric hospital. Read More

Mediastinal tumors comprise a range of congenital, neoplastic and inflammatory tumors. While many benign and malignant lesions can be differentiated by CT appearance and attenuation values, many cannot be reliably separated. The purpose of this paper is to evaluate the feasibility of dual-energy computed tomography (DECT) in differentiating a spectrum of mediastinal tumors in children Read More
