Chest magnetic resonance imaging: a protocol suggestion

Abstract

In the recent years, with the development of ultrafast sequences, magnetic resonance imaging (MRI) has been established as a valuable diagnostic modality in body imaging. Because of improvements in speed and image quality, MRI is now ready for routine clinical use also in the study of pulmonary diseases. The main advantage of MRI of the lungs is its unique combination of morphological and functional assessment in a single imaging session. In this article, the authors review most technical aspects and suggest a protocol for performing chest MRI. The authors also describe the three major clinical indications for MRI of the lungs: staging of lung tumors; evaluation of pulmonary vascular diseases; and investigation of pulmonary abnormalities in patients who should not be exposed to radiation.

Dilemma of diagnosing thoracic sarcoidosis in tuberculosis-endemic regions: An imaging-based approach. Part 2

“…A multiplanar and multisequence protocol consisting of breath-hold and free breathing sequences is preferred. [ 11 14 ] Fat-saturated sequences are an essential component of the protocol as they enhance the conspicuity of fluid as well as ghosting artifact of chest wall[ 12 ] (STIR and T2W multivane fat suppressed in the suggested protocol). Fast sequences (HASTE) with short acquisition times are recommended.…”

Comparison of magnetic resonance imaging and computed tomography to measure preoperative parameters of children with pectus excavatum

“…The multi‐echo 2‐point DIXON (mDIXON) scanning sequence is a novel technique that allows for fast scanning that can be completed during breath‐holding . Furthermore, we noticed that three‐ dimensional T1‐weighted (3DT1) MRI allows chest scanning with free breathing …”

“…18,19 Furthermore, we noticed that threedimensional T1-weighted (3DT1) MRI allows chest scanning with free breathing. 20 Therefore, we sought to use non-invasive MRI examinations to obtain inspiratory and expiratory phase lung volume measurements in children with PE, and compared the results with volume reconstructions of thoracic CT scanning. We hypothesized that if the noninvasive MRI examination could be used to evaluate lung volume, we could obtain more comprehensive results while avoiding the potential radiation damage caused by CT scanning.…”

Rapid MRI of the lungs in children with pulmonary infections

“…We read with interest the review article entitled "Chest magnetic resonance imaging: a protocol suggestion" by Hochhegger et al ( 1 ) . The authors have reviewed the technical aspects and suggested a protocol for performing chest MRI.…”
