Introduction: The purpose of this study is to provide a classification of different types of hepatic hydatid cysts by measuring the mean apparent diffusion coefficient (ADC) and exponential apparent diffusion coefficient (EADC) using diffusion-weighted magnetic resonance imaging (MRI). Methods: A total of 60 patients (42 female, 18 male) and 79 lesions were included in this retrospective study. The patients were diagnosed with hepatic cyst lesions for various reasons according to the hospital's abdominal MRI records, and therefore all patients had their diagnosis pathologically or serologically confirmed. ADC and EADC maps were obtained with values of b0, and b400 s/mm 2 , and mean ADC and EADC values were calculated for each lesion. Then, the mean value calculated for each cyst type is compared. Results: Regarding ADC values, we determined a statistically significant difference between types 1 and 4, types 2 and 4, and types 3 and 4 (p=0.001). When we compared EADC values, we found that EADC values of WHO type 4 lesions were higher than WHO type 1,2, and 5 lesions (p=0.001). Also, we divided our patients' lesions into two groups, namely active (types 1,2,3) and inactive (types 4,5) lesions. When we compared each group's mean ADC and EADC values, we determined a difference between active and inactive groups. When compared to inactive groups, ADC values of active lesions were higher, and EADC values were lower, as shown by statistics. Conclusion: Our study shows that ADC and EADC values may be useful for the differentiation of type 4 lesions from other types, and distinguishing of active and inactive groups.

“…Koken et al (17) study investigated 92 lesions of 54 patients by creating ADC maps using b50, b500, and b1000 values. When the ADC values were compared according to lesion groups, there was no significant difference between type 1 and 2, 3; type 2 and 3; type 3 and 4; or type 4 and 5.…”

“…The size of a SLC is usually < 1 cm but can grow up to 30 cm according to reports in the literature (21). In two studies with 92 and 136 HC lesions, the mean cyst sizes were 7.2 AE 3.6 cm (range ¼ 2.05-21.6 cm) and 7.1 AE 3.1 cm, respectively (20,22). In our study, mean size of the SLCs and type I HCs were found to be 2.59 AE 1.23 cm (range ¼ 1.2-7.6 cm) and 7.49 AE 2.95 cm (range ¼ 2.8-14 cm), respectively.…”

“…In previous studies, apparent diffusion coefficient (ADC) values obtained at diffusion-weighted MRI (DWI) were evaluated for the discrimination of subgroups of HCs (14)(15)(16)(17)(18)(19)(20). Only a few studies with a limited number of cases aimed to evaluate the efficiency of ADC values on differentiation of type I HCs and SLCs (15)(16)(17)(18).…”

Background Determining the nature of purely cystic hepatic lesions is essential because different kinds have different follow-ups, treatment options, and complications. Purpose To explore the potential of apparent diffusion coefficient (ADC) values of diffusion-weighted imaging (DWI) for the differentiation of type I hydatid cysts (HC) and simple liver cysts (SLC), which have similar radiological appearances. Material and Methods This single-center prospective study was conducted during 2016–2019. Round, homogenous, anechoic liver cysts >1 cm were classified according to at least two years of imaging follow-up, radiological features, serology, as well as puncture aspiration injection reaspiration procedure and pathology results. ADC values of 95 cysts (50 type I HCs and 45 SLCs) were calculated on DWI. The differences in ADC values were analyzed by independent t-test. Results Of 51 patients, 28 were female, 23 were male (mean age 32.07 ± 22.95 years; age range 5–82 years). Mean diameter of 45 SLCs was 2.59 ± 1.23 cm (range 1.2–7.6 cm) and ADCmean value was 3.03 ± 0.47 (range 2.64–5.85) while mean diameter of 50 type I HCs was 7.49 ± 2.95 cm (range 2.8–14 cm) and ADCmean value was 2.99 ± 0.29 (range 2.36–3.83). There was no statistically significant difference in ADC values between type I HCs and SLCs Conclusion Some studies report that ADC values of type I HCs are statistically significantly lower than those of SLCs. Others suggest no significant difference. In our study with a higher number of cases, using ADC parameters similar to those in previous studies, we did not find any statistically significant difference.

“…Die Datenlage zum Stellenwert der Diffusionswichtung ist heterogen. Der ADC-Wert von inaktiven Zysten ist kleiner als der von aktiven Zysten [23]. Eine Differenzierung von WHO-CE1 Zysten und blanden dysontogenetischen Leberzysten dürfte mit der DWI nicht möglich sein [24].…”

Background Cystic (CE) and alveolar (AE) echinococcoses are zoonotic parasitoses that may pose diagnostic problems due to their relative rarity in Middle Europe. Methods Based on a recent literature search and the observation of casuistics from a national echinococcosis treatment center, epidemiological, radiological, and therapeutic fundamentals are presented and important differences between AE and CE are discussed. Results and Conclusion AE and CE must be regarded as completely different diseases, which differ from each other in every significant aspect. This applies not only to the epidemiological background of the patients but also to the biology of the diseases and their respective imaging features. Key Points: Citation Format
