Inhance Suite includes:

Inhance Inflow IR, a non-contrast-enhanced MR angiography technique that has been developed to image arteries with ability to suppress static background tissue and venous flow. This sequence is based on 3D FIESTA, which provides excellent signal-to-noise ratio (SNR) and produces bright blood images. Selective inversion pulses are applied over the region of interest to invert arterial, venous, and static tissue. At the null point of the background tissue, an excitation pulse is applied to generate signal. The net result is an angiographic image with excellent background suppression and free of venous contamination. It helps you achieve uniform fat suppression using a spectrally selective chemical saturation (SPECIAL) technique, while respiratory gating compatibility reduces respiratory motion artifacts during free-breathing renal exams.

Inhance 3D Velocity, designed to acquire angiographic images in brain and renal arteries with excellent background suppression in a short scan time. By combining a volumetric 3D phase contrast acquisition with parallel imaging, efficient k-space sampling, and pulse sequence optimization, Inhance 3D Velocity is capable of obtaining the whole neurovascular anatomy in approximately five to six minutes. Furthermore, background suppression is improved by the optimized pulse sequence design, resulting in better visualization of small branches. Respiratory triggering is also compatible with Inhance 3D Velocity to enable abdominal angiography, specifically renal arteries. The results are excellent productivity and image quality.

Inhance 2D Inflow, a pulse sequence designed to acquire angiographic images of arteries that follow almost a straight path (i.e. femoral, popliteal, and carotid arteries). Arterial blood flow is faster during the systolic phase and slows down during the diastolic phase. Therefore, Inhance 2D Inflow is designed to acquire data during the systolic phase. It features an optimized spatial saturation gap to improve fat suppression and background suppression. Peripheral Gating is deployed to minimize the pulsatile artifacts. Inhance 2D Inflow is compatible with ASSET acceleration to reduce scan time.
