This study used state-of-the-art MR techniques with phased array body coils, breath-hold sequences which included T1-weighted images with fat saturation before and after intravenous gadolinium chelate.
The exams were conducted on a 3-T scanner (Magnetom Skyra, Siemens Healthcare Sector, Erlangen, Germany) in a supine position, with electrocardiographic triggering, dedicated cardiac surface coils, and expiratory breath holds.
The exhalation port of the mask was attached via a stainless steel tube to a convoluted polytetrafluoroethylene breath containment coil in an adjoining room.
The breath containment coil (899 cm × 1.3 cm i.d)., which is based on the alveolar breath sampling device developed by Raymer et al. (1990), provides a sufficiently large buffer volume (1.1 L) that ensures that the breath being sampled is primarily alveolar because it is from the end of the expiration.
MRI was performed at our institution in 67 of the 72 cases on a 1.5-T system (Symphony/Avanto; Siemens Healthcare, Erlangen, Germany) using a body phased array coil and a breath-holding technique.
Current MR techniques using phased-array torso coils, thin slices, and dynamic gadolinium-enhanced breath-hold gradient-echo (GRE) sequences are optimal for imaging pancreatic carcinoma, and in some studies have outperformed CT especially in the detection of smaller tumors.
And a bit of condensation from a player's breath adhering to the inside of a coil can lead to cracked notes, or "clams".
The smoke coiled up counterclockwise and, every few minutes, the warm breath of a terrible smell would arrive with the wind.
Reduced sensitivity due to the increased distance between receive coil-array and the heart, breathing problems, affecting breath-hold, resulting in variable breath-hold times, and/or ECG detachment due to sweating may place additional constraints on the application of H-MRS in this patient group.
Enraged, she transforms herself into a great serpent; he hides within a bell in the Dojoji temple; she, coiling herself around the bell, scorches him to death with her fiery breath.
We used coil embolization to treat pulmonary sequestration in order to prevent infection and shortness of breath and to determine whether asymptomatic patients should be treated by this method.
