Vision-based markerless registration using stereo vision and an augmented reality surgical navigation system: a pilot study
BMC Medical Imaging - Tập 15 - Trang 1-11 - 2015
This study evaluated the use of an augmented reality navigation system that
provides a markerless registration system using stereo vision in oral and
maxillofacial surgery. A feasibility study was performed on a subject, wherein a
stereo camera was used for tracking and markerless registration. The computed
tomography data obtained from the volunteer was used to create an integral
videography imag...
A comparative analysis of diffusion-weighted imaging and ultrasound in thyroid nodules
BMC Medical Imaging - Tập 19 - Trang 1-6 - 2019
Diffusion-weighted imaging (DWI) and ultrasound are commonly used methods to
examine thyroid nodules, but their comparative value is rarely studied. We
evaluated the utility of DWI and ultrasound in differentiating benign and
malignant thyroid nodules. A total of 100 patients with 137 nodules who
underwent both DWI and ultrasound before operation were enrolled. The T1 and T2
signal intensity ratio...
Đánh giá các mạng nơ-ron tích chập cho việc phát hiện chuyển động giữa các lần nín thở từ một chồng hình ảnh cắt ngang tim Dịch bởi AI
BMC Medical Imaging - Tập 23 - Trang 1-10 - 2023
Nghiên cứu này nhằm phát triển và xác thực một phương pháp dựa trên học sâu để

Preoperative prediction of microsatellite instability status in colorectal cancer based on a multiphasic enhanced CT radiomics nomogram model
BMC Medical Imaging - - 2024
To investigate the value of a nomogram model based on the combination of
clinical-CT features and multiphasic enhanced CT radiomics for the preoperative
prediction of the microsatellite instability (MSI) status in colorectal cancer
(CRC) patients. A total of 347 patients with a pathological diagnosis of
colorectal adenocarcinoma, including 276 microsatellite stabilized (MSS)
patients and 71 MSI pa...
The impact of cardiopulmonary hemodynamic factors in volumetry for pulmonary nodule management
BMC Medical Imaging - - 2022
Abstract Background The acceptance of coronary CT angiogram (CCTA) scans in the
management of stable angina has led to an exponential increase in studies
performed and reported incidental findings, including pulmonary nodules (PN).
Using low-dose CT scans, volumetry tools are used in growth assessment and risk
stratification of PN between 5 and 8 mm in diameter. Volumetry of PN could also
benefit ...
Identification of radiomic biomarkers in a set of four skeletal muscle groups on Dixon MRI of the NAKO MR study
BMC Medical Imaging - Tập 23 - Trang 1-23 - 2023
In this work, we propose a processing pipeline for the extraction and
identification of meaningful radiomics biomarkers in skeletal muscle tissue as
displayed using Dixon-weighted MRI. Diverse and robust radiomics features can be
identified that may be of aid in the accurate quantification e.g. varying
degrees of sarcopenia in respective muscles of large cohorts. As such, the
approach comprises th...
Performances of clinical characteristics and radiological findings in identifying COVID-19 from suspected cases
BMC Medical Imaging - Tập 22 - Trang 1-14 - 2022
To identify effective factors and establish a model to distinguish COVID-19
patients from suspected cases. The clinical characteristics, laboratory results
and initial chest CT findings of suspected COVID-19 patients in 3 institutions
were retrospectively reviewed. Univariate and multivariate logistic regression
were performed to identify significant features. A nomogram was constructed,
with cali...
Correlation between the area of high-signal intensity on SPIO-enhanced MR imaging and the pathologic size of sentinel node metastases in breast cancer patients with positive sentinel nodes
BMC Medical Imaging - Tập 13 - Trang 1-7 - 2013
We previously demonstrated that superparamagnetic iron oxide (SPIO)-enhanced MR
imaging is promising for the detection of metastases in sentinel nodes localized
by CT-lymphography in patients with breast cancer. The purpose of this study was
to determine the predictive criteria of the size of nodal metastases with
SPIO-enhanced MR imaging in breast cancer, with histopathologic findings as
referenc...
Analysis of CT signs, radiomic features and clinical characteristics for delta variant COVID-19 patients with different vaccination status
BMC Medical Imaging - Tập 22 - Trang 1-12 - 2022
To explore the characteristics of peripheral blood, high resolution computed
tomography (HRCT) imaging and the radiomics signature (RadScore) in patients
infected with delta variant virus under different coronavirus disease (COVID-19)
vaccination status. 123 patients with delta variant virus infection collected
from November 1, 2021 to March 1, 2022 were analyzed retrospectively. According
to COVI...
