Background: This study aims to compare the conventional magneticresonance imaging and cine-magnetic resonance imaging findings with the operation results in terms of invasion existence in esophageal cancer. Methods: This prospective study included a total of 37 suspected cases (21 males, 16 females; mean age 63.3 years; range 28 to 81 years) with respect to whether or not invasion in esophageal masses between January 2012 and February 2016. Initially, conventional magnetic resonance imaging (T-1-weighted, T-2-weighted, short tau inversion recovery), lesion characteristics and invasion areas were evaluated in all cases. The cases with invasion were re-evaluated according to dynamic moving features of the lesion and adjacent tissue by cine-magnetic resonance imaging in three planes. The relative motion of the mass with adjacent tissues, fatty planes, and invasion status were evaluated according to size and structure. Results: The presence of invasion was detected by conventional magnetic resonance imaging in all of the cases. Invasion was not detected in 28 of 37 cases, while it was observed in nine cases by cine-magnetic resonance imaging. Twenty of 28 non-invasion cases were operated and results were compatible with the cine-magnetic resonance imaging results. The remaining eight cases were not operated due to severe comorbidities and the refusal of operation. Conclusion: Cine-magnetic resonance imaging may contribute to detect invasion accurately in esophagus cancer which is adjacent to moving tissues such as heart and main vascular structures. Based on our study results, cine-magnetic resonance imaging appears to be superior to conventional magnetic resonance imaging.
Doubling Time in Pulmonary and Hepatic Hydatid Cysts
(Baycinar Medical Publ-baycinar Tibbi Yayincilik, 2024) Aydin, Yener; Ozgokce, Mesut; Ulas, Ali Bilal; Durmaz, Fatma; Kasali, Kamber; Eren, Suat; Eroglu, Atilla
Background: This study aims to investigate whether the concept of doubling time in hydatid cysts differs according to different parameters such as age, sex, and whether the cyst is located in the lung or liver. Methods: Between January 2012 and August 2023, a total of 138 hydatid cysts were retrospectively analyzed. There were 55 pulmonary (32 males, 23 females; mean age: 25.6 +/- 23.8 years; range, 2 to 77 years) and 83 hepatic hydatid cyst patients (32 males, 51 females; mean age: 31.1 +/- 22.8 years; range, 3 to 75 years). Results: The mean doubling times for pulmonary and hepatic hydatid cysts were 73.4 +/- 41.8 and 172.6 +/- 108.8 days, respectively (p<0.001). When children (<= 18 years old) and adult cases were compared for pulmonary hydatid cysts, the mean doubling times were 61.1 +/- 17.6 and 87.1 +/- 55.3 days, respectively (p=0.119), and for hepatic hydatid cysts, 110.6 +/- 48.4 and 215.6 +/- 118.3 days, respectively (p<0.001). While comparing male and female cases, the mean doubling time for pulmonary hydatid cysts was 77.6 +/- 32.2 and 67.6 +/- 52.6 days, respectively (p=0.018), while for hepatic hydatid cysts, it was 192.0 +/- 111.7 and 160.4 +/- 106.2 days, respectively (p=0.250). Conclusion: The doubling time seems to be approximately 10 weeks in the lung and approximately 25 weeks in the liver. Hydatid cysts grow faster in children than adults in both the lungs and liver.
