Objective. The study aimed to compare the diagnostic value of different methods of assessing the condition of the scar on the uterus after a cesarean section.Materials and methods. A comparative analysis of the diagnostic value of assessing the validity of the scar on the uterus in the pre-graviridar period and during pregnancy ultrasound (ultrasound) investigation with dopplerometry (DM), magnetic resonance imaging (MRI), and microwave radiothermometry (RTM). The study included fertile patients after delivery by cesarean section (n = 56), at the planning stage, during pregnancy and after delivery, both through natural birth pathways and by re-cesarean section.Results. A comparative analysis of the assessment of the scar in the uterus by the mentioned methods revealed the comparable diagnostic value of these methods during the planning phase of pregnancy and in gestation time 11–12 and 20 –21 weeks, while at the period of 37–38 weeks, the sensitivity of RTM was significantly (1.6 times) higher than ultrasound investigation.Conclusions. Despite the high diagnostic effectiveness of all three methods of assessing the condition of the uterine scar after cesarean section, the method of microwave radiothermometry has advantages in the simplicity of the method, lack of need for expensive equipment, and specialized qualifications of the doctor.

The Individual

Findings in 34 patients with traumatic brachial plexus injury documented by surgical exploration and intra-operative somatosensory-evoked potentials were correlated with findings on myelography and magnetic resonance imaging (MRI) to determine whether MRI can identify nerve root avulsion. The coronal and sagittal planes were not able to demonstrate avulsion of the individual nerve roots. The axial and axial oblique planes did provide useful information to determine which nerve root was avulsed in the upper plexus, although it was difficult to clearly delineate the lower cervical rootlets. The accuracy of MRI was 73% for C5 and 64% for C6 and that of myelograpby 63% for C5 and 64% for C6. Thus, the diagnostic accuracy of MRI for upper nerve roots was slightly superior to myelography. Although its primary diagnostic value is limited to the upper nerve roots whose avulsion is relatively difficult to diagnose by myelography, MRI can provide useful guidance in the waiting period prior to surgical exploration after brachial plexus injury.

Introduction: We aimed to introduce the diagnostic value of diffusion-weighted (DWI) magnetic resonance imaging (MRI) for distinguishing benign and malignant renal cystic masses.Methods: Abdominal DWI-MRIs of patients with Bosniak categories 2F, 3, and 4 cystic renal masses were evaluated retrospectively. Cystic masses were assigned as benign or malignant according to histopathological or followup MRI findings and compared with apparent diffusion coefficient (ADC) values.Results: There were 30 patients (18 males and 12 females, mean age was 59.23 ± 12.08 years [range 38‒83 years]) with cystic renal masses (eight Bosniak category 2F, 12 Bosniak category 3, 10 Bosniak category 4). Among them, 14 cysts were diagnosed as benign and 16 as malignant by followup imaging or histopathological findings. For the malignant lesions, the mean ADC values were lower than for benign lesions (p=0.001). An ADC value of ≤2.28 x10-6 mm2/s or less had a sensitivity of 75% and a specificity of 92.86% for detecting malignancy.Conclusions: ADC can improve the diagnostic performance of MRI in the evaluation of complex renal cysts when used together with conventional MRI sequences.

Objective This study aimed to determine the diagnostic value of magnetic resonance imaging (MRI), hysteroscopy, and laparoscopy to avoid unnecessary treatment when patients present with clinical manifestations that are close to those of gestational trophoblastic neoplasia (GTN). Methods Three patients who were falsely diagnosed with presumed GTN and received needless chemotherapy in our hospital from July 2011 to March 2012 were studied. We also reviewed data of patients with similar clinical features who were diagnosed as having residual pregnancy in recent years. Clinical manifestations were evaluated. Results All three patients had persistently high serum β-human chorionic gonadotrophin levels and a mass with abundant blood supply in the uterus after termination of pregnancy. The patients were diagnosed with GTN and underwent chemotherapy. They responded poorly to chemotherapy and underwent surgery. The pathological diagnosis in all patients was residual pregnancy. In recent years, no patients were misdiagnosed because pelvic MRI, hysteroscopy, or laparoscopy was used when residual pregnancy could not be excluded. Conclusion Gynecologists should diagnose carefully when patients present with clinical manifestations that are close to those of GTN to avoid unnecessary treatment. MRI, hysteroscopy, and laparoscopy could be important examinations for excluding residual pregnancy.

Computed tomography (CT) and magnetic resonance imaging (MRI) are enabling more precise diagnosis and treatment planning in patients with diseases of the larynx. The aim of this article is to describe the role of these methods in assessment of the laringeal diseases and key local anatomic characteristics important for spread of the disease. CT and MRI have a valuable contribution to the staging of the tumors due to the possibility to show the relationship to the ventricular complex, involvement of the subumucosal spaces, defining craniocaudal and anterposterior extension, laringeal cartilage invasion, as well as regional lymph node metastases.

Ameloblastoma is an odontogenic tumor that shares clinical and imaging characteristics with other lesions of the jaws, such as odontogenic keratocyst, which makes the diagnosis difficult. However, in addition to radiographic and tomographic examinations, Magnetic Resonance Imaging (MRI) has been increasingly used, contributing with relevant additional information about the differentiation between solid and liquid components of the lesion. This case report was conducted to present two variations of ameloblastoma and discuss the radiographic, tomographic and MRI contribution in the differential diagnosis between ameloblastoma and odontogenic keratocyst.The signal intensity in T1-weighted MRI revealed internal fluid content in both cases, which was important in the differential diagnosis with other intraosseous lesions such as odontogenic keratocysts. This is probably due to the presence of keratin that increases the viscosity of the content and also for an intermediate signal intensity signal in T2-weighted MRI. Therefore, MRI revealed important internal characteristics of the reported lesions, which was very useful in the establishment of the differential diagnosis with other lesions.

Abstract Massive subchorionic thrombosis (MST) is defined as a massive thrombosis under the chorionic plate, and is responsible for obstetric complications. We encountered two cases of MST. Placental abruption was misdiagnosed by ultrasound examination in Case 1, and a cesarean section was performed at 33 weeks of gestation. Magnetic resonance imaging (MRI) at 21 weeks of gestation suggested MST in Case 2. A cesarean section was performed at 26 weeks’ gestation because of pregnancy-induced hypertension, fetal growth restriction and non-reassuring fetal status.

Uterine Scar

The frequency of the Cesarean section leads to increase number of the patients with the scar on the uterus. In the Clinical hospital № 1 (Smolensk, Russia) the childbirth is carried out through natural birth canal on the women having a reliable scar on the uterus. The analysis of the vaginal delivery and labour outcomes in 69 patients with the scar on the uterus is carried out. The childbirth in 38 patients was conducted with the epidurals, in 31 patients – without this type of anesthesia. The efficiency and safety of the epidural anesthesia are shown. The obtained results confirm that the epidural anesthesia doesn´t complicate the labour, doesn´t increase the hospitalization term, doesn´t influence the bleeding and negative effects on the fetus condition and the newborn assessment according to Apgar score. The possibility of using epidural anesthesia at childbirth on the women with uterine scar during the dystocia is shown.
