REVIEW
Erik Su, Nicholas Dalesio, Aliaksei Pustavoitau
Ultrasound has increasingly become a clinical asset in the hands of the anesthesiologist and intensivist who cares for children. Though many applications for ultrasound parallel adult modalities, children as always are not simply small adults and benefit from the application of ultrasound to their management in various ways. Body composition and size are important factors that affect ultrasound performance in the child, as are the pathologies that may uniquely afflict children and aspects of procedures unique to this patient population...

Phase-contrast cine MRI (PC-MRI) is the gold-standard non-invasive technique for measuring vessel blood flow and has previously been applied in the human fetal circulation. We aimed to assess the feasibility of using PC-MRI to define the distribution of the fetal circulation in sheep. Fetuses were catheterized at 119-120 days gestation (term, 150 days) and underwent MRI at 123 days gestation under isoflurane anesthesia, ventilated at a FiO2 of 1.0. PC-MRI was performed using a fetal arterial blood pressure catheter signal for cardiac triggering...

Thrombus formation can lead to heart attacks, stroke and pulmonary embolism, which are major causes of mortality. Current standard diagnostic imaging methods detect anatomic abnormalities such as vascular flow impairment but have limitations. By using a targeted molecular imaging approach critical components of a pathology can be selectively visualized and exploited for an improved diagnosis and patient management. The GPIIb/IIIa receptor is abundantly and specifically exposed on activated platelets and is the key receptor in thrombus formation...

Heart failure with preserved ejection fraction (HFpEF) affects more women than men, suggesting gender to play a major role in disease evolution. However, studies investigating gender differences in HFpEF are limited. In the present study we aimed to describe gender differences in a well-characterized HFpEF cohort. Consecutive HFpEF patients underwent invasive hemodynamic assessment, cardiac magnetic resonance imaging and exercise testing. Study endpoints were: cardiac death, a combined endpoint of HF hospitalization or cardiac death and all-cause death...

PURPOSE: Differentiating between systemic sclerosis-related interstitial lung disease (SSc-ILD) and idiopathic pulmonary fibrosis (IPF) is important because of the differences in workup, prognosis, and treatment. However, there is much overlap in the appearance of these 2 entities on high-resolution computed tomography. We propose that inflammation and/or fibrosis focally or disproportionately involving the bilateral anterolateral upper lobes and posterosuperior lower lobes ["Four Corners" Sign (FCS)] is specific for SSc-ILD...

A 52-year-old man developed interstitial pneumonitis during treatment with desvenlafaxine for major depressive disorder. The man received desvenlafaxine at 50 mg for symptoms of depression 4 years earlier. Six months after a dose increase to 100 mg, he developed bronchitic symptoms with mild, persistent dyspnea. Investigations revealed a restrictive pattern on pulmonary function testing, bilateral upper lobe reticular opacities with traction bronchiectasis on radiology imaging, and end-stage interstitial fibrosis with honeycomb changes consistent with chronic hypersensitivity pneumonitis on open lung biopsy...

PURPOSE: The deformable registration of pulmonary computed tomography images before and after radiation therapy is challenging due to anatomic changes from radiation fibrosis. We hypothesize that a line-enhanced registration algorithm can reduce landmark error over the entire lung, including the irradiated regions, when compared to an intensity-based deformable registration algorithm. MATERIALS: Two intensity-based B-spline deformable registration algorithms of pre-radiation therapy and post-radiation therapy images were compared...

Raine syndrome is a rare osteosclerotic bone dysplasia characterized by craniofacial anomalies and intracranial calcification. Most patients with Raine syndrome are of Arab ancestry and die during the neonatal period. We herein report a Japanese patient with non-lethal Raine syndrome who presented with characteristic cerebral hyperechogenicity and a hypoplastic nose by fetal ultrasonography. She was admitted to the NICU due to pyriform aperture stenosis. Craniofacial abnormalities, intracranial calcification, osteosclerosis, chondrodysplasia punctata, and a mutation of FAM20C was identified...

To investigate the effect of breath-holding on left-to-right shunts in patients with a secundum atrial septal defect (ASD). Thirty-five consecutive patients with secundum ASDs underwent right heart catheterization and invasive oximetry. Phase-contrast magnetic resonance imaging (MRI) was performed for the main pulmonary artery and ascending aorta. All measurements were obtained during free breathing (FB) (quiet breathing; no breath-hold), expiratory breath-hold (EBH), and inspiratory breath-hold (IBH). Pulmonary circulation flow (Qp) and systemic circulation flow (Qs) were calculated by multiplying the heart rate by the stroke volume...

2-Deoxy-2-(18Fluorine)-fluoro-D-glucose (FDG) positron emission tomography/computed tomography (PET/CT) is an integral part of lung carcinoma staging and frequently used in the assessment of solitary pulmonary nodules. However, a limitation of conventional 3D PET/CT when imaging the thorax is its susceptibility to motion artefact which blurs the signal from the lesion resulting in inaccurate representation of size and metabolic activity. Respiratory gated (4D) PET/CT aims to negate the effects of motion artefact and provide a more accurate interpretation of pulmonary nodules and lymphadenopathy...
