Single Shot Technique
 
In single shot techniques (used for EPI, TSE, FSE, RARE, HASTE), the entire raw data set is acquired with a single excitation pulse. The magnetization of a fully relaxed spin system is used. Each of the subsequent echoes is given a different phase encoding. For improved SNR, spatial resolution or FOV, the needed raw data are acquired over a number of sequence repetitions. Each repetition then collects a fraction of the complete raw data set. Only slightly more than a half of the raw data is acquired. The image is obtained through half Fourier reconstruction.
A single shot sequence is useful in cases where movement is to expect e.g. in abdominal Imaging or fetal MRI.

Single turn solenoid is a transmit and receive RF imaging coil that, in general, has a cylindrical shape. The solenoidal configuration of this coil is a further developed planar surface coil. While surface coils have a strong coupling and high signal to noise ratio to nearby signals they have a marked loss of signal beyond one radius from the center of the coil. With a solenoidal coil design the imaging object lies within one radius from the coil center, which improved imaging (of extremities, such as wrist or knee).

Single Volume Spectroscopy
 
(SVS) This method maps the metabolic information from the VOI in a spectrum. Single volume techniques are advantageous in case of pathological changes that cannot spatially be limited to a few VOI; by using local volume sensitive shim the local magnetic field inhomogeneity can be compensated.
