The aim of this study was to describe visualisation rate and appearance of all pericardial sinuses and recesses and to evaluate whether there is a significant difference between visualisation of these sinuses and recesses on 2-, 4-, 16- and 64-slice multidetector computed tomography (MDCT).

Materials and methods

We retrospectively analysed 588 MDCT scans of the chest obtained with a protocol for pulmonary embolism.


The visualisation rate of any pericardial recess was 85.2%. The rates on 2-, 4-, 16- and 64-slice MDCT were 74.7%, 90.6%, 90.3% and 88.7%, respectively. There was a statistically significant difference in visualisation rates of pericardial recesses between 2-slice MDCT and other MDCT systems (p<0.01). Age, and 4-, 16- and 64-slice MDCT versus 2-slice MDCT and the presence of pleural effusion appeared as significant predictors of the presence of any recess.


Visualisation rates of pericardial recesses are higher with 4-, 16- and 64-slice MDCT than with 2-slice MDCT. Therefore, radiologists need to be familiar with the different appearances of pericardial recesses on MDCT to avoid misdiagnosis.

Valutazione dei seni e recessi pericardici con TC multistrato a 2-, 4-, 16- e 64- strati



Descrivere frequenza e aspetto di tutti i seni e recessi pericardici e valutare se vi sia differenza significativa nella loro visualizzazione con la tomografia computerizzata multidetettore (TCMS) a 2-, 4-, 16- o 64-strati.

Materiali e metodi

Sono stati retrospettivamente analizzati 588 esami TCMS del torace ottenuti con protocollo di studio per embolia polmonare.


I recessi pericardici sono stati visualizzati nell’85,2% dei casi. La frequenza di visualizzazione con la TCMS a 2-, 4-, 16- e 64-strati è stata rispettivamente del 74,7%, 90,6%, 90,3% e 88,7%. La differenza nella frequenza di identificazione dei recessi pericardici è risultata significativa tra la TCMS a 2 strati e le TCMS con differente numero di strati (p<0,01). L’età del paziente, l’utilizzo della TCMS a 4-, 16- e 64-strati piuttosto che della TCMS a 2 strati e la presenza di effusione pleurica sono risultati essere significativamente correlati con la presenza di recessi.


Il tasso di visualizzazione di recessi pericardici con la TCMS a 4-, 16- e 64-strati è risultato superiore rispetto a quello con la TCMS a 2 strati. Di conseguenza è necessario approfondire la conoscenza degli aspetti variabili dei recessi pericardici con la TCMS per evitare diagnosi errate.
