    Notes: Abstract. Skeletal muscle is one of the most unusual sites of metastasis from any malignancy. We report a patient with rapidly progressive contractures due to metastatic infiltration of a carcinoma of unknown origin into the skeletal muscle. This 61-year-old man presented with a 1-month history of rapidly evolving, painful restriction of mobility of his right arm and his legs. Computed tomography showed diffuse metastatic nodules in all muscles, particularly in the hip abductors. Muscle biopsy revealed extensive infiltration of the muscle with carcinoma cells.

    Notes: Abstract. The purpose of our study was to evaluate the capability of a subsecond spiral-CT scanner using two contrast medium phases in staging of colorectal cancer. In our study we included 37 patients with proven rectum or colon carcinoma. Spiral CT was performed following tap-water enema of the colon in the arterial and venous phases of contrast medium enhancement. Our results were compared with the findings of pathological examination after surgery. The tumor's size and extension were evaluated in the arterial and venous phases, the lymph nodes in the venous phase of the CT scan. The tumor was in the rectum (n = 14), sigma (n = 11), descending colon (n = 6), and cecum (n = 6). Two-phase spiral CT had a sensitivity of 97.2 % in the arterial phase and 89.1 % in the venous phase in detecting the carcinoma. The staging results were in the arterial phase in 30 of 37 cases (81.0 %) and in the venous phase in 24 of 37 cases (64.8 %) according to pathology. In 27 of 32 patients (84.3 %) lymph nodes were detected. The correct classification of the N-stage was possible in 23 of 34 cases (67.6 %). The combined use of arterial and venous phases in staging of colorectal cancer can improve the T- and N-stage classification in comparison with using only one contrast medium phase. The arterial phase is superior compared with the venous phase for local tumor staging and the venous phase is used for lymph node assessment.

    Notes: Abstract. The purpose of this study was to evaluate the capabilities of subsecond spiral CT in detecting and staging of gastric cancer. Our study included 40 patients with endoscopically detected gastric carcinomas. Two-phase spiral CT was performed within one breathhold each. Distension of the stomach was achieved by intravenous application of scopolamine and drinking of 500 ml water. After bolus injection of contrast medium, scanning was performed in the arterial and venous phase. Gastric tumour extention and lymph node involvement was assessed. Gastric cancer was detected in 39 of 40 cases (sensitivity 97.5 %). Location of the tumour was correctly assessed in all cases. In 31 of the 39 cases (79.4 %) CT staging was accordant with pathological staging. One hundred two (70 %) of 145 nodes infiltrated by tumour tissue were detected and 144 (42.8 %) of 336 nodes free of metastatic involvement were found. The predictive values of positive and negative results for the detection of lymph node metastases were 67.1 and 75 %, respectively. Spiral CT is recommended for staging of gastric cancer.

    Description / Table of Contents: Summary The introduction on spiral computed tomography (spiral CT) has vastly enriched the methodological diversity of computer-tomographic scans. It allows for the recording of different perfusion or excretion stages of the kidney parenchyma of the urine draining paths by carrying out long-distance, phase-identical multiple examinations of the retroperitoneum. The description of the findings which are characterized by their local and contrasts behavior is possible. The following report describes the indications and technological process of kidney spiral CT using kidney-typical intravenous contrast media. Special emphasis is put on the advantages and limits of multiple phase spiral CT. Decisive preconditions are: 1. specific clinical query, 2. selection of the corresponding phase contrasts of the kidneys and uretra or bladder, 3. exact technical and temporal adjustment of the acquisition parameters. Scanning times are in the range of seconds. The overall examination can be carried out quick and without any major strain on the part of the patient. A sound proof and a general differentiation of focal kidney lesions can be derived from the acquired data. This is also true for kidneys and ureters findings. Bladder findings can be localized and differentiated according to stage. More than two „spiral acquisitions” should be carried out with re- straint taking exposure to radiation into account. Due to the sound registration of focal lesions, its capability of reproduction and its short-time examination, the spiral CT of the kidneys can be said to be the most effective current scanning method of the retroperitoneum following clinical examinations and sonography.
    Notes: Zusammenfassung Mit der Einführung der Spiral-Computertomographie (Spiral-CT) sind die methodischen Möglichkeiten der computertomographischen Schnittbilddiagnostik erheblich erweitert worden. So können durch länger- streckige, phasenidentische Mehrfachuntersuchungen des Retroperitoneums unterschiedliche Perfusions- bzw. Ausscheidungsphasen des Nierenparenchyms und der harnableitenden Wege erfaßt werden. Die Darstellung von Befunden, die sich durch ihre Lokalisation oder ihr Kontrastverhalten unterscheiden, ist somit möglich. Im vorliegenden Beitrag werden die Indikationen und technische Durchführung der Nieren-Spiral-CT unter Einsatz nierengängiger intravenöser Kontrastmittel beschrieben. Besonders wird auf die Vorteile und die Grenzen der Mehrphasen-Spiral-CT bei der Diagnostik fokaler Nierenläsionen eingegangen. Entscheidende Voraussetzungen sind: 1. Gezielte klinische Fragestellung, 2. Auswahl der entsprechenden Phasenkontrastierung der Nieren und Ureteren bzw. der Harnblase und 3. exakte technische und zeitliche Abstimmung der Akquisitionsparameter unter Berücksichtigung der Perfusionsverhältnisse entsprechender fokaler Nierenveränderungen. Die Scanzeiten liegen im Bereich von Sekunden. Die Gesamtuntersuchung ist schnell und für den Patienten wenig belastend durchführbar. Die Untersuchungsergebnisse erlauben vor allem einen treffsicheren Nachweis und eine weitgehende Differenzierung fokaler Nierenläsionen. Nierenbecken- bzw. ureterständige Befunde sind erfaßbar. Blasenbefunde können lokalisiert und stadienabhängig eingeordnet werden. Zurückhaltung ist bei mehr als 2 „Spiralakquisitionen” im Hinblick auf die Strahlenbelastung geboten. Die Spiral-CT der Nieren stellt aufgrund ihrer sicheren Erfassung fokaler Läsionen, ihrer Reproduzierbarkeit und der schnellen Untersuchungsführung derzeit das effektivste Schnittbildverfahren des Retroperitoneums dar. Nach klinischer Untersuchung und Sonographie ist die Nieren-CT entscheidender Bestandteil der Basisdiagnostik unklarer Befunde des Retroperitoneums.
