Non-traumatic thoracic emergencies: acute chest pain: diagnostic strategies

Lorenzo Bonomo; Francesca Di Fabio; Anna Rita Larici; Biagio Merlino; Maria Luigia Storto

Abstract. Acute chest pain may represent the initial and/or accompanying symptom in a variety of disease processes that may occur in the cardiovascular system, respiratory system, gastrointestinal tract, or musculoskeletal system. Although clinical history, risk factors, and physical examination are important factors in establishing the etiology of symptoms in patients presenting with acute chest pain, imaging modalities are frequently utilized. Noncardiac causes of acute chest pain are reviewed in this paper with special reference to the most recently published literature and emphasis on acute aortic diseases. Imaging modalities with indication of appropriateness, optimal technique and practical keys for interpretation are discussed.

Missed lung cancer: when, where, and why?

Missed lung cancer is a source of concern among radiologists and an important medicolegal challenge. In 90% of the cases, errors in diagnosis of lung cancer occur on chest radiographs. It may be challenging for radiologists to distinguish a lung lesion from bones, pulmonary vessels, mediastinal structures, and other complex anatomical structures on chest radiographs. Nevertheless, lung cancer can also be overlooked on computed tomography (CT) scans, regardless of the context, either if a clinical or radiologic suspect exists or for other reasons. Awareness of the possible causes of overlooking a pulmonary lesion can give radiologists a chance to reduce the occurrence of this eventuality. Various factors contribute to a misdiagnosis of lung cancer on chest radiographs and on CT, often very similar in nature to each other. Observer error is the most significant one and comprises scanning error, recognition error, decision-making error, and satisfaction of search. Tumor characteristics such as lesion size, conspicuity, and location are also crucial in this context. Even technical aspects can contribute to the probability of skipping lung cancer, including image quality and patient positioning and movement. Albeit it is hard to remove missed lung cancer completely, strategies to reduce observer error and methods to improve technique and automated detection may be valuable in reducing its likelihood.

Purpose The aim of this study was to investigate the relationship between whole-tumor CT perfusion and FDG PET/CT parameters in non–small cell lung cancer (NSCLC). Methods Twenty-five patients with NSCLC were prospectively included. CT perfusion parameters calculated were blood flow (BF), blood volume (BV), mean transit time, and peak enhancement intensity. SUVmax, SUVpeak, SUVmean, metabolic tumor volume (MTV), and total lesion glycolysis (TLG) were evaluated for PET/CT. Tumor diameter and volume were measured, and lesions were divided according to maximum axial diameter in more than 3 cm and 3 cm or less. The correlations between CT perfusion and PET/CT parameters were assessed in all tumors, as well as according to tumor diameter and volume. Results Lesion diameter and volume showed a negative correlation with BF and BV (r = −0.78, −0.78, −0.57, −0.48, respectively) and a positive correlation with mean transit time (r = 0.55, 0.65, respectively). The negative correlation between BF and lesion diameter and volume was confirmed in the subgroup of lesions of more than 3 cm (r = −0.68, −0.68, respectively). A positive correlation between SUVmax, SUVpeak, SUVmean, and lesion volume was observed (r = 0.50, 0.50, 0.46, respectively) and confirmed in lesions 3 cm or less (r = 0.81, 0.79, 0.78, respectively). Metabolic tumor volume and TLG showed a positive correlation with lesion diameter and volume in the overall population (r = 0.93, 0.87, 0.88, 0.90, respectively) and in lesions of more than 3 cm (r = 0.89, 0.84, 0.84, 0.79, respectively). Blood flow and BV showed a negative correlation with MTV and TLG (r = −0.77, −0.74, and −0.58, −0.48, respectively) in the overall population and with MTV in lesions of more than 3 cm (r = −0.69, −0.62, respectively). Conclusions Perfusion and metabolic parameters seem to depend on tumor size. The bigger the tumor, the lower the BF and the BV and, conversely, the higher the SUVpeak, MTV, and TLG. This information would be useful in the clinical setting when diagnosing or treating NSCLC, especially with novel therapies and/or for radiation treatment modulation.
