“…Patients with full or partial pneumonectomy, for example, will be challenged with MRI's longer apneic pauses. Vascular imaging with CT or MRI, in our experience and available literature, has almost identical clinical value when performed with contrast for both tumor invasion and pulmonary embolism caused by neoplasms 9 . For pulmonary embolism, CT is highly preferred than MRI as it is faster and the patient can receive critical care if needed by using normal hospital equipment.…”

“…Currently, CTPA remains the gold standard for the diagnosis of PE as well as for PI and its complications [ 23 ]. However, results of a meta-analysis have suggested that the specificity and sensitivity of Magnetic Resonance Imaging (MRI) are slightly better than CTPA ones for the detection of acute PE [ 40 ]. Furthermore, MRI successfully identified PI on post-mortem examination [ 41 ].…”

“…Furthermore, MRI successfully identified PI on post-mortem examination [ 41 ]. Therefore, MRI could be useful when CTPA is insufficient for the diagnosis of PI, thus helping in the differential diagnosis of alternative causes of parenchymal opacity [ 40 ]. Furthermore, MRI could discriminate the time of occurrence of PI.…”

Pulmonary infarction (PI) is a possible consequence of pulmonary embolism (PE). The real incidence of PI could be underestimated considering only non-fatal PE presentation. However, following postmortem examination, the prevalence of PI is considerably higher. This evidence suggests the necessity of proper diagnostic protocol for identifying PI. Unfortunately, PI diagnosis can sometimes be challenging, due to the overlapping of symptoms with other diseases. Nowadays, the diagnosis is mainly based on radiological evaluation, although the combination with emerging imaging techniques such as ultrasound and nuclear scanning might improve the diagnostic algorithm for PI. This review aims to summarize the available data on the prevalence of PI, the main predisposing factors for the development of PI among patients with PE, to resume the possible diagnostic tools, and finally the clinical and prognostic implications.

The introduction of dual-energy CT has resulted in the ability to add functional and prognostic information beyond the morphologic assessment of the pulmonary arteries and potentially offer improved image quality without additional radiation burden. New approaches and strategies in CT scanning have resulted in decreased radiation exposure as well as a significant decrease in contrast material used without decreasing the sensitivity for detection of pulmonary embolism. Continuous developments and improvements in MR angiography techniques offer a valuable and efficient option for certain patient populations without the risk of radiation exposure. Improvements in the technical success rate and reliability of this modality will mean more widespread use in the future. Moving beyond planar ventilation/perfusion (V/Q) scintigraphy, nuclear imaging offers several new approaches, including the use of single photon emission computed tomography (SPECT) and SPECT/CT resulting in superior diagnostic performance and a decrease in nondiagnostic studies, potentially surpassing the diagnostic capabilities of computed tomography pulmonary angiography. Ongoing research in the use of V/Q PET/CT demonstrates superior temporal and spatial resolution and quantitative capabilities compared to SPECT-CT; this modality will likely play an increasing role in the detection and characterization of pulmonary embolism. The field of pulmonary embolism imaging has demonstrated continuous evolution in both development of novel techniques and improvement in current technologies, resulting in better detection, decreased radiation exposure, and enhanced functional information beyond morphologic characterization of the pulmonary vasculature.

Comparison between CT and MRI in the assessment of pulmonary embolism

Abstract: This meta-analysis demonstrates that MRI has better sensitivity and specificity in detecting subsegmental artery PE. MRI is a relatively better detection technique for PE. This conclusion is consistent with many published researches.
