Methods, systems and computer program products of magnetic resonance imaging (MRI) using ultra short echo times and spiral sampling in k-space are disclosed. A long inversion radio frequency (RF) pulse that inverts magnetization of long Tcomponents are applied to a sample that exhibits long transverse relaxation time (T) components and short Tcomponents to minimize signals corresponding to the long Tcomponents. In addition, half RF excitation pulses are applied to the sample to select one or more echo times. Data corresponding to the selected one or more echo times are acquired using a spiral trajectory, and a first echo image is obtained based on the acquired data.

Magnetic resonance imaging (MRI) using ultra short echo times and spiral sampling in K-space

Systems and techniques for imagining samples including components with small values of T. Optionally, the systems and techniques may provide (for example) suppression of unwanted signals, enhanced contrast, and artifact control in imaging samples with small values of T.
