1.
Kamona N, Ng J, Kim Y, D Vu B, Vossough A, Wagner C, et al.
Acad Radiol . 2024 Sep; 31(11):4629-4642. PMID: 39242296
Rationale And Objectives: The emergence of low-dose protocols for CT imaging has mitigated pediatric radiation exposure, yet ionizing radiation remains a concern for children with complex craniofacial conditions requiring repeated...
2.
Vu B, Kamona N, Kim Y, Ng J, Jones B, Wehrli F, et al.
Magn Reson Med . 2024 Sep; 93(1):245-260. PMID: 39219299
Purpose: Ultrashort echo time (UTE) MRI can be a radiation-free alternative to CT for craniofacial imaging of pediatric patients. However, unlike CT, bone-specific MR imaging is limited by long scan...

Kim J, Lee H, Oh S, Jang J, Lee H
J Imaging Inform Med . 2024 Feb; 37(2):563-574. PMID: 38343224
Knowledge of input blood to the brain, which is represented as total cerebral blood flow (tCBF), is important in evaluating brain health. Phase-contrast (PC) magnetic resonance imaging (MRI) enables blood...

Lee H, Xu J, Fernandez-Seara M, Wehrli F
J Cereb Blood Flow Metab . 2024 Jan; 44(7):1184-1198. PMID: 38289876
Quantitative BOLD (qBOLD) MRI allows evaluation of oxidative metabolism of the brain based purely on an endogenous contrast mechanism. The method quantifies deoxygenated blood volume (DBV) and hemoglobin oxygen saturation...

Deshpande R, Langham M, Lee H, Kamona N, Wehrli F
Magn Reson Med . 2023 Dec; 91(5):2057-2073. PMID: 38146669
Purpose: Renal metabolic rate of oxygen (rMRO ) is a potentially important biomarker of kidney function. The key parameters for rMRO quantification include blood flow rate (BFR) and venous oxygen...

Kamona N, Jones B, Lee H, Song H, Rajapakse C, Wagner C, et al.
MAGMA . 2023 Nov; 37(1):83-92. PMID: 37934295
Objectives: CT is the clinical standard for surgical planning of craniofacial abnormalities in pediatric patients. This study evaluated three MRI cranial bone imaging techniques for their strengths and limitations as...

Vu B, Jones B, Lee H, Kamona N, Deshpande R, Wehrli F, et al.
Bone . 2023 Sep; 177:116900. PMID: 37714503
Background: Assessment of proximal femur trabecular bone microstructure in vivo by magnetic resonance imaging has recently been validated for acquiring information independent of bone mineral density in osteoporotic patients. However,...

Biondetti E, Cho J, Lee H
Neuroimage . 2023 May; 276:120189. PMID: 37230206
This article provides an overview of MRI methods exploiting magnetic susceptibility properties of blood to assess cerebral oxygen metabolism, including the tissue oxygen extraction fraction (OEF) and the cerebral metabolic...

Jones B, Wehrli F, Kamona N, Deshpande R, Vu B, Song H, et al.
Bone . 2023 Mar; 171:116743. PMID: 36958542
Background: Assessment of cortical bone porosity and geometry by imaging in vivo can provide useful information about bone quality that is independent of bone mineral density (BMD). Ultrashort echo time...

Caporale A, Barclay A, Xu J, Rao H, Lee H, Langham M, et al.
J Cereb Blood Flow Metab . 2023 Mar; 43(8):1340-1350. PMID: 36927172
Sleep, a state of reduced consciousness, affects brain oxygen metabolism and lowers cerebral metabolic rate of oxygen (CMRO). Previously, we quantified CMRO during sleep via Fick's Principle, with a single-band...
