Despite uncertainties with the use of digital breast tomosynthesis (DBT), also called 3D mammography, clinical interest is increasing. Some researchers and patient advocacy groups are promoting its ability to improve breast cancer screenings. Preliminary studies suggest that tomosynthesis has increased specificity and sensitivity over 2D digital mammography (DM), and therefore reduced recall an...

Subarachnoid hemorrhage secondary to ruptured aneurysm is a critical clinical situation demanding a very skilled surgical and medical management. Until now cerebral digital subtraction angiography (DSA) has been used as the criterion standard for aneurysmal detection and planning of their microsurgical treatment. However, as the method for diagnosis of subarachnoid hemorrhage moved from lumbar ...

Optical Coherence Tomography (OCT) technology introduces speckle, an insidious form of multiplicative noise which degrades the quality of OCT images. In this paper order statistics filters like Mean, Median, Min, Max and Alpha Trimmed Mean are implemented on digital image and OCT images. The images were tested with two different mask sizes of 5*5 and 7*7. The objective evaluation of both the ty...

INTRODUCTION Dynamic image acquisition protocols are increasingly used in emission tomography for drug development and clinical research. As such, there is a need for computational phantoms to accurately describe both the spatial and temporal distribution of radiotracers, also accounting for periodic and non-periodic physiological processes occurring during data acquisition. METHODS A new 5D ...

We have developed spectrally encoded photoacoustic microscopy using a digital mirror device for multi-wavelength tomography, which enables fast spectral imaging of optical absorption. The optical illumination wavelengths are multiplexed at a laser pulse repetition rate of ≈ 2 kHz. Liquid samples, whole blood, and blood vessels in mouse ears were imaged. Compared with internal wavelength tuning ...

The future of diagnostic imaging will rely, in large part, on the digital revolution that is currently affecting all technologydriven disciplines. Superimposed on the digital substrate, however, are a variety of wide-ranging developments that are modality-specific advancements in image receptor technology and modality-specific image data reduction. Diagnostic imaging is classically divided into...

BACKGROUND Visceral artery pseudoaneurysms are relatively rare but have a high mortality rate in case of rupture. Their detection in the last decades is rising due to an increased use of computed tomography and angiography. However, due to the nonspecific nature of the clinical symptoms and signs, diagnosis is often delayed or missed. We describe two cases of patients presenting with nonspecifi...

Veterinary diagnostic imaging has grown tremendously in the past 10 years. Digital radiology and cross sectional imaging modalities like ultrasound, computed tomography (CT), and magnetic resonance imaging (MRI) have profoundly improved our ability to diagnose many small animal diseases. Digital radiography improves image quality while at the same time making radiographs easy to make and share ...

INTRODUCTION Although the importance of the bronchial arteries is evident in modern day thoracic surgery, the significance of their communications with coronary arteries has yet to be appreciated, especially in cases of heart-lung transplantation and aortic aneurysm repair. We conducted a study to demonstrate the coronary-bronchial anastomotic routes in a porcine model using angiography and com...
